Mucho improvement Camp. I think your faces are looking great. Your right about the hair, it pretty much looks like a photoshop 'hair brush', being applied.

Here's the deal... Photo reference. Go grab a membership to www.3d.sk (warning: site contains blatant images of penises, and other normally concealed human organs!!) and download their hi-res photos. Unbeatable stuff there, with dozens of male, female, old, young, pretty, ugly, faces to choose from, posed at all angles. (well, not ALL angles). If you can't afford a membership, send me a private message, and I will let you borrow some of my personal reference images. Right now, for 14 dollars, you can get a 1 month membership to 3d.sk and it's sister website http://www.environment-textures.com/ , which has thousands of hi-res environmental photos. Just sit their and download like crazy for your month membership...it's what I did.

Take those photos, get some hair that you like, drop it into photoshop and just work it into your skins.

Game modeling is moving further away from stylized lowpoly models and simplistic textures. The next gen games are pushing the realism borders, by using shaders, normal mapping, specular and bump mapping. If you are wanting to get into skinning for hl2 mods, start using photos, pushing realism and studying up on advanced mapping.
