So i am an 'artist', well i'm learning to become one, and yes, i like to make signatures and that stuff, but what i prefer is to sketch things, and thats my problem, i can sketch them, well not that good, but then i want to color it in with photoshop BUT my computer is really weird and it hasn't got any memory left, so i'm screwed..

I will also post some tutorials on making signatures in Gimp, something free that looks like Photoshop..
