Improving a drawing scan

Hi, I scanned a CD cover ad I'm trying to improve on the scan. What are some tips for "smoothing" the image? As it stands, you tend to see all the pixels that make up the drawing. I'd like to give it a smoother look so the image doesn't look so choppy. Thanks, L -- Penguin Power!
