That helmet tho I think that one is spot on with kinda like a classic feel to it.
If I'm not mistaken, in the canon Samus can form the suit around her with her mind. In that case it's not necessary to make the suit industrial-looking (or the arm cannon that big) or have the paint stripes mentioned above, since Samus doesn't have to go buy parts to weld in place to upgrade anything. Also those glow plugs (bolts?) look bad, I get the blizzard look but I would change those and make them not come out of the suit like that. Something that wouldn't be necessary for someone that can form the suit around them.
I like everything EXCEPT the caution stripes on her thighs. The caution stripes look terrible. Take them off.
After i uploaded the wireframe of my most recent aircraft and strongly suggested people DO NOT use it as a reference for how to model correctly, i received a lot of questions asking what i would do differently and why it matters. So i took a few pieces of my aircraft and rebuilt them to illustrate the difference between a concept mesh and a sub-d production mesh (for film). When i self taught myself 3d i had no idea what i was doing and how i was meant to properly model so something like this might be helpful to some people. I wanted to write more in here but there is a type limit so a brief explanation is at the bottom.
The post is concluded with a written breakdown by the artist:
