Fun with Illustrator

In the process of deciding which designs I want to upload to my business site, I started to play around with ways to make them look like more than just flat drawings on a computer screen. Since I don't have physical samples to take photos of, my digital images have to look great. Here are two samples I did this morning.

Do they look professional? Does the fact that it's not a photograph of ink and paper detract from the design itself?
