I like the re-design, but it looks like it would be at home in Halo then Metroid. Not saying that it would be a bad thing, not at all. Just something seems a bit off with the armor design. Samus, on the other hand, looks right at home, and pretty sweet in her in new look. Overall, you did a good job.
I really like the redesigned Justin Bailey undersuit, but not feeling the armor. If I'd at all put it to words, I'd say it emphasizes her femininity a bit much. The classic Varia Suit and Power Suit are more "all business"
