Illustrations in Work

My name is Terry and I am currently in the process of writing a humorous book about politics. I decided early on that I wanted to feature illustrations to correspond with my chapters so I had a friend of mine provide the illustrations. I promised him that I'd help advertise his work so I thought I'd post a link to his portfolio in case any other authors were looking for an artist to illustrate their books. So here it is: ward.carbonmade.com/. My friend produces inexpensive, quality work. I hope this doesn't sound too much like a commercial. Thanks guys.
