Download the Artist Form (pdf) and send me your replies by email. It has a few questions like what kind of work you do, what games do you do work for, quality of work, etc... things to help gamers find you based on what they are looking for in an artist.
Once I get the completed form, I'll get you added to the site in the categories you listed so that folks can find you easily and you can get to work. You can see what a sample listing looks like below.
There is NO monthly cost to be listed as an artist on this site.
At this point, I have not set up the system to update Artist profiles with new images. It is in the works right now and will be implemented in the future once I get everything in place.
I have decided that I will run the site free of charge in order to help artists who are starting out. As I continue to build the site, I will be offering the chance for artists and companies to advertise their painting services on the front page as well.
