You've got a pretty solid character design going, but those giant nipples are distracting me, lol. That's not exactly a character flaw or anything though. I like the dinky little straps going on. Would prefer not having a white outline around him though. Maybe a more complimentary color. It kinda hurts my eyes, just the contrast, and makes him hard to look at. The high contrast should be on your character, not around him. Otherwise, fine!
