Stumbled across this site looking at some gimp guides. Very cool! I created an account so I can view some of the map artwork! It has been a long, long time since I have created any, maybe I can find some old ones to post. Lately I've been uploading my textures and brushes to share with others. You can find them at http://www.texturemate.com , they may be useful for creating some cool grungy paper effects! I have been told I need more paper textures and am currently working on it...
