I have looked at your work on Deviant Art and I do like it. The mine is the perfect style for many of our adventure maps, whilst the top down scenes we can use for our Wraith recon products without any issue.
Most the work we do is black and white, although the occassional colour piece is commissioned as well. Contact me on firstname.lastname@example.org and we can discuss how much you charge. If you want work I may have a couple of pieces that I need doing immediately (am waiting to hear back from one of our regular arists to see if he can do the work).
All the best
