Hmm...not bad.
But check Cg Talk, and you'll see what i mean.

Several -not all- of those are already pros. usually get only in a free project if they really lov ethe idea, seriously. Many work at CG films, tv.
Yep, those guys you mentioned seem to do good art. yet though you always need to consider the human, organic models. Is where most people fail noticeabily. Doing a ship, or weapons, even a robot, though may sound strange, is easier. though of course, is also complex. this is a very personal opinion, not something to take as totally certain.
But i know what you mean. there are options to pick a guy in the university believing it'll serve as portfolio.
I don't know. Sometimes it does, but often it wont do. Me for example, I don't really need it anymore, most artist just build up their protfolio with max renders (brazil or not) and basicly showing all their abilities, humans, creatures, weapons, levels, the wider the best.
I think they guys that do an amateur game for porfolio, in what is getting a job..I dont think is really effective, though sometimes may do.
I have seen many times ppl getting art jobs the standard Max based way...sending the zip files in CD or whatever, with the cover letter.
Dunno, I have been called even without a serious portfolio, just showing model shots.
I personally wouldn't need that, and I tell you I'm not a genius. Just a 2d/3d guy.
But yep, there are many -mostly students- that yet think this way, that usually don't have to pay the flat, and that somewhat mind less getting in a free , amateur project without being paid or well paid.
So, yes, you can find them. But with some quality wont be easy.Anyway, of course I wish you good luck
IMHO, the ideal target is not the typical artist (we'r most the times unemployed people, or employed with a killing number of hours a day working like mad in games) , but someone that is good at art, and has a solid, not stressing job to pay the rent. And that happens to like the project you'r doing or wanting to do.
Even MUCH better if ur good friends. But consider then u will not want to argue with a very good friend

and in projects this happens in occassions.
There are certain quake2 mods where I have seen terrificly good people. But they were die hard for Quake2, Nostalgia was killing them... I doubt one of those would move a finger for a full game project otherwise...
But yep, world is big, and coders find free artists, so I'm saying a full bag of nonsenses...
