very nice....the cartoon characters, their yours? or is it the background and text is what you designed? didnt see any CP
I really like the first one's effect...cloud like....the text i feel could use something..whether it be a fine pixel outline of a red....or a glow, yet if its the face you want to be prominant...a  glow or color added then the opacity changed to give it the effect its in the clouds. I'd say 8/10

Cool background on the second...makes one feel they are from hell lol im not familiar with the charactures... 9/10

good work...i remember using the gimp many moons ago, before going to PSP
