Check out what this guys been using as a subject:
I've been saving off images with the "intention" of painting them. Mostly from around Manhattan. I personally don't care that "good artists" never paint from a flat subject. What I like about the google images is that you can look up at buildings from interesting angles. I've got quite a collection saved but they're scattered all over my disks. (sound familiar?) Yes, my disks are as cluttered as my house. Help me.
