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"
I'm a big Nintendo fan, love the Metroid series. I own most, and I've played and liked every game. Yes, even Other M, which for some reason unbeknownst to me everyone else claiming to be a fan of the series, hate. Most of the suits in the game have the same general design. But what you've done? This, is badass! Would love to see you try to redesign some of the other suits in the series.
Number 1, there are absolutely no ponies in my portfolio. Number 2, questioning of overt and/or unnecessary sexual content is actually very reasonable. Number 3, the whole purpose of this site is for artists to post their artwork, not for some talentless loser to go around calling people names because he thinks they're somehow wrong for pointing out the obvious.
And exactly how many realistic outfits have you been drawing on women? Two or zero, maybe? Seriously, though. My artwork may not look very good to you, but at least I don't make girls' clothing look like literal spray paint the majority of the time that I draw them. In fact, that's pretty much one of my major goals.
By the way, the stuff I have on this site is only a small fraction of what I've drawn before. Just you wait.
