It's hard to trace this when we don't know what half the variables are used for, or what the surrounding code context is. Post some more, perhaps?

MS Paint is entirely capable of producing fine, raster art, given a good artist with experience in said program.
I'm still going to finish it eventually though, so don't be too sad. I'm going to come right out and ask for code help.
