I like your Captain America battle suit. Inspired by the upcoming Avengers movie, perhaps? Even so, it actually looks slightly better than the movie version, as far as the helmet goes. In the movie, it looks more like an expensive novelty mask. Your version has it actually resemble a helmet, and the armored gloves and boots are necessary for a character whose powers are mainly human abilities boosted to their absolute peak potential, which obviously does not include being bulletproof. The texture of the suit reminds me of tactical body armor, which would also be appropriate for a super-soldier character like Captain America. Great work.
