I managed to paint in Samus' colors. Beware, this is a png with transparency, so if you're running an older version of IE it may not look as intended.
I'm struggling with what scene to put her in. I'm thinking either the pink areas of Ridley's hideout or in Kraid's hideout. Either way, I'm going to work in an Energy Tank. I'm not sure if a dead enemy (that she presumably just shot) should be included as well.
Part of the problem with drawing the character without context is putting her into context or scene and making it look like she belongs there. You have to worry about perspective, lighting, and scale.
