Pin Ups and Illustrator

So... seeing as I have some free time on my hands, i think I'm gunna take a crack at using Illustrator more. My cousin is a pretty good artist, although her artistic efforts are cut short by her parents. She has recently been doing some Pin up girl art. It looks pretty darn good if you ask me. I think that if she went on to maybe digitize the sketches she might be able to get more out of it. So... I'm taking a shot at making her pieces of art, into really nice, editable line art. If there are any suggestions, feel free to leave a comment, i could use the help. I'll be posting up some before and after images soon.
