I did this as my final painting in my drawing class this past semester, completed in GIMP.
And apparently, my professor has some sort of aversion to digital paintings, and he refused to give me any feedback whatsoever on this piece unless it was printed out. I never did get around to doing that, but I did send him the file in an email, in which I apologized for poor time management. I also said that I would really appreciate if he took the time to let me know what he thought of it. He didn’t. =/
But whatever, I got a B in that class, and I probably won’t have any more classes with that guy anyway.
