Okay, I know it's kind of ugly, but let me explain.
I saw a movie on YouTube about a guy repainting the Mona Lisa using MS Paint, in 2.5 hours. My father looked at it, and suggested he was using a print of the original painting under his tablet, and thus he was just copying it.
So, I thought: why don't try to use such a technique? I took one of my recent pen drawing, put it under my tablet cover and then started painting it in Painter™ using a media I've never really used: acrylics.
