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.
Have a look at an amazing gallery of concept images behind canceled Star Wars Battlefront 4 from a British developer Free Radical Design. The collection dates back to 2006 when the game was in the planning stages. Sadly, Battlefront 3 project was shut down, so the fourth part was just a dream.
This is a kind-of ‘what if?’ scenario with stories of the Star Wars prequels taking different paths. The game would tell a story of the universe where Anakin killed Yoda and murdered Padmé. What is more, Obi-Wan and Luke would have joined the dark side. The fun part is that Darth Maul and Count Dooku would have been Jedi. What a crazy scenario, right?
