Hi there I run a group called ARTWORK-A-THON ATTACK that specializes in getting artists acknowledged by game developement teams. I involve the developers of said game to get them to see and aknowledge your artwork submitted. We run competitions in conjunction with the development houses for the games that we have chosen and the winner normally wins the game (or if they own it already) other games to the value of the game up for grabs in the competition. There is normally a theme around the game the artist has to submit artwork for. Plus its a great way to get you artwork exposed.

If you would be interested in joining we have one on the go already for Neverending Nightmares and the creator Matt Gilenbach is involved in helping curate. I see you have already done some excellent artwork. You can read more if you are interested below

http://steamcommunity.com/groups/ARTACK and in the HOW TO ENTER GUIDE in the forums.

Thank you for your time
