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.
Take a look at two pictures. One is a photo by cosplayer Shirogane-sama, as Nier: Automata’s 2B. The other one is a 3D recreation from Chauliac Romain. Looks crazy, right?
The 3D model looks so realistic that it is hard to tell the difference. The artist used Maya, Arnold and ZBrush to create an astonishing piece, and you have to admit that the result is something else.
