Thank you for the feedback, Sasquatch and Ashaman!
Sounds perfect for a small and/or indie developer; someone with a shoestring budget who can't afford programmers and artists. Unfortunately, they won't be able to afford to pay very well, either--if at all--but at least you'll know it's because they genuinely don't have the cash, and not because the execs are paying themselves much, much more than they're worth.
I'd definetly be fine with joining any indie project. I've done a couple small game projects myself, but I'd find the experience of working in a team invaluable, paid or not paid.
If I had to make a suggestion, I'd say you should try adding color; it's hard to read pure black and white.
Yes, I definetly need to post some of my color works. Sadly, a lot of my colored works are large canvas watercolor and pastel which don't lend themselves kindly to my very small scanner. :(
I fear, that concept art is not really helpful in this situation, but a good knowledge about the common art tools (PS, ZBrush, Maya/Max) and a solid background in art (color/light theory etc.) could be a plus.
Thanks for the advice! I'll definetly look into getting better acquainted with some common art tools. I had previously used PS for a while, but it'd be nice to also become fluent in other art tools. And also, thank you very much for the link. :)
