Giby your work is truly astonishingly beautiful! I feel as if it's almost 100x better than any graphics a GM:S Game could handle, though. If I were you I'd start taking work on http://www.freelancer.com.
There are a lot of people out there who need artwork at level that you can produce. People are willing to pay upwards of $200 of these kinds of things. I wish you luck! Keep up the good work.
