Have you ever tried to draw something, but couldn’t find a good picture? Then two weeks later a good picture showed up in the paper. Most artists keep what they call reference files of things that interest them. Since I have recently moved my studio I have had to downsize that file a bit. I use the internet, but pictures are usually small and low in detail, so if you see a good picture of things that you usually draw don’t be afraid to cut them out and save them. Just make sure Dad has finished reading the paper first. Good Luck!
