I do environment modelling so I have hardly any experience in char modelling, but my entire graduating class went into character so I had to sit through all those classes too. Not sure how many hours you're planning to put into the character, or how hi-res it will be in game or how much realism you're going for,, but some suggestions for improving the final if you get the time to, small details that could make a big difference

Anyways~ Of course besides defining the crotch a bit, all those other addition are simply for stylizing/silhouette and making it more striking in game-play, and since I'm not sure how far you are taking the concept into the character or how the style of game is, its just a suggestions I really feel guilty commenting in any character modellers work, since I can't even get close haha. Great work overall! It'll be fun to do the accessories :> (props were always my favourite part @_@)
