i was hoping to get this working as a head model, but i'm getting the impression that it won't fit in with nexuiz's sci-fi theme. i think that's not a bad thing though, it's good that nexuiz has a consistent theme because it makes the game more immersive than a jumble of styles. maybe i'll make a little mod for nexuiz instead.
the neck was just something i made when i first started modelling. there's no real point in it so i've removed it and now it looks a lot more like a head model.
i'm going to start making a low poly model next and then try and find out how to generate a normal map using the subsurf model as a guide.
