UPDATING THE DESIGN: ALIEN WARRIOR
"It's all beautifully done, everything, the designs and the way they're executed." - H.R. Giger about the design of Aliens in ALIENS. Cinefantastique Magazine May 1988
"Well, there are a number of reasons (why H.R. Giger didn't
return). One, he was doing Poltergeist II, and we didn't know exactly how long
that commitment was, but we heard that he was busy. But honestly, I think that
if we had really wanted to fight for him, we could have worked around it.
However, we already had Syd Mead, and Ron Cobb, involved. Both of them are
designers who were also working on other projects at the same time. And I didn't
want to deal with yet another designer who was also working on another project.
The other thing is that I wanted to personally take charge of that aspect of the
design. I knew Syd was going to handle some of the fantastic high tech hardware
of the future; Ron was going to deal with the Colony. I just wanted an area for
myself." - - James Cameron, lofficcier.com
"They're (aliens) mainly a reprise of Mr. Giger's design" - James Cameron, lofficcier.com
The Alien head in the first film was very smooth. The top of the head was very smooth. Underneath it had a skull shape and a ribbed design and originally it was designed to see that through that kind of transparent surface in the Giger design. I thought that what was underneath the surface was more interesting than the final look - James Cameron, Aliens Collector's Edition Commentary
"It's evident that the makers of the sequel had a great respect for the original Alien which Winston himself remembers as "the best horror movie of the decade". For this reason, the design concepts for the facehugger, the chestburster and the warrior aliens remain relatively unchanged" - Galactic Journal magazine #21 1986
Then there were the fully grown warrior aliens that Winston wanted to move away from "the man in a costume" look of the original - Cinescape magazine 1997
The Alien in the first movie wasn't a full adult yet - the individual in ALIEN never reached maturity. In time his head would get ridges and would transform into a fully adult creature that we see in 'Aliens'. The young alien of the first movie looked pretty much the same as the adult underneath the dome. Aliens are "born" with a smooth head, and this cover falls off after a while, exposing the ridges. Supporting this thesis, the chestburster in "Aliens" had a smooth head.
"Overall the design is the same as the first film's" (Alien Comparison Chart). There are some subtle differences in the body, but nothing that could be called a redesign or original, just slight alterations. First of all, the body is much much slimmer and the limbs thinner to make the alien look even less human-like and to eliminate the human-like posture. That is a direct continuation of the the original idea with a better execution. In the original movie, the tallest and the thinnest person they could find was hired to play alien in three scenes. In Aliens, the alien is even taller and even slimmer thanks to the advancements in puppetry and animatronics. This time a puppet could be used for certain scenes
"(The puppets) stand almost eight feet tall - the same size as, yet even thinner than, the original alien" - Stan Winston, Aliens Official Movie Magazine 1986

"I had access to just about anything except the original chestburster. But there have been a number of and books of the alien , so anything we didn't have actual access to, we had pictures of. We tried to be as true to the original film as we could, without disallowing ourselves a little bit of artistic freedom to do things that we considered - if not improvements. The alien warriors were the only instance where Winston wished the design could have been charged for the sequel. "The weakness - if there was a weakness - to the first film, was that there was this wonderful monster the alien, that we saw, and didn't see, throughout the entire movie - and then, at the end, when we did see it, when its finally blown out of the hatch, what we saw was a man in the suit, which for me, personally, was a letdown." - Stan Winston, Aliens Official Movie Magazine 1986
The aliens from ALIENS have the same head design/"decorations" as Giger's alien had in the first movie under the dome sans the skull face (meaning no eye or nose sockets).

The skull's temporal (side indents) remained. There's an addition of ridges to the head which isn't really an addition or a change because they were already designed and covered by the dome in the original movie. The exact same ridges and dragon headspike row were designed by H.R. Giger and done on the original alien. The difference is that they were hidden by the dome and airbrushed instead of sculpted.

The neck is one of the very few redesigns (others include the hands and feet) and was slightly altered. It kept the same patterns but pulled them in different directions.

There were no design changes done to the torso whatsoever except for the addition of two extra ribs due to alien's increased height and slimmer body. All the biomechanical designs and parts remained the same

The back, the tubes and the spiked head support remained unchanged.

The hands however, were significantly redesigned . The number of fingers was reduced and the hands got elongated, making it less human and less glove-like in appearance.
John Rosengrant: Hands matched the inner small arms of the Queen alien to look less “manlike”
Then there were the fully grown warrior aliens that Winston wanted to move away from "the man in a costume" look of the original - Cinescape magazine 1997
"We've redesigned the
hands so that they are longer than original, the fingers are a little bit longer
- again, we took certain licenses to get away from the human look of a hand
in a glove; and then we've developed articulated mechanical hands for close-ups,
which do things that a person's hand in a glove couldn't do" -
Stan Winston, Aliens Official Movie Magazine 1986
The arms didn't change much or didn't change at all, depending on the suit. The arms were different on the stunt suits than on the animatronic puppets. The arms on the full suit hero suits had virtually no redesign. Only the oval "grill" was wider. The spandex stunt suits followed that but featured only the parts that were catching the highlights from the shadows. The arms of the puppet however, had noticeable changes. They were much thinner and the biomechanical designs on them were much larger.

The appendages on the elbows got elongated (as a part of natural growing process)...
... and the feet were slightly altered so they will look less human. The toes were redesigned.

All those differences seem like a natural changes in the maturing process. The body gets slimmer and the limbs grow longer. There were no real major changes, and certainly not substantial enough to be called redesigning or original (with the exception of hands). Those are rather cosmetic changes done mostly to make the concept even better with better special effects and technology advancement.
