Trio Pointillism

Last year in art class we had to do a pointillism of an 8x10 black and white photo, and this is mine. I honestly thought it was bad, but apparently my teacher liked it because she put it on the school website. If you couldn't tell, it's Harry, Ron, and Hermione and the cat is Mrs. Norris. (If you don't know who Mrs. Norris is, go read the books!)
