he has a rough kutku style model on one of his pages, right now hes more armor / weapons modeling icon wise until he can get the code notch is supposed to release, one notch releases some code thing he can go full development on it.
I could of swore that i saw a topic in the texture pack forum ages ago that said monster hunter. Excuse me i this is outdated http://www.minecraftforum.net/topic/212742-64x15monster-hunter-themewip/ saw it like 1-2 months ago i think :/
Edit: Just realized this was a texture pack, not a mod. 'lol'. Carry on with discussion. Although i do think the texture pack looks pretty :3
