very interesting arm design. a more realistic concept to her arm cannon. not dogging on the original design i do love it but this is easier to see. only if there were more visual wires connected from the arm to the gun. unconditionally though, your art is beautiful. well done.
Not really, the suit is supposed to be part of her body and explanation of how that all works is the very reason everyone isn't wearing one. To change that is to remove a big portion of the mythos leaving holes. If you just make it just a suit instead then you'd have to justify why everyone isn't making use of them given that the Galactic Federation has access to all of the Chozo knowledge and technology. It would really only end with Samus suffering form special snowflake syndrome which is already bad enough with what Retro did.
This is a very interesting approach and really well done. It's similar to mine in that we both went the route of making the suit look more feminine, although mine looks a bit more pointy and alien, while yours looks more human. I do like how the gauntlet on the right arm was made the color of the cannon while giving Samus a smaller gun, that's an interesting approach.
