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.
Zacharias Reinhardt has published a video guide on how to set up everything properly in Blender and start retopologizing your work.

4. Properties Editor -> Modifier -> Add Modifier:
