Here is a web site banner made with Photoshop that I did for a local business. http://www.bookmans.us/undefined
Several changes were made, it originally had a wing tip shoe but that was too simular to another article about the same subject.
As an artist, photoshop montages are almost too easy to make, it seems like cheating some how. Still involves composition, controling values, supporting a theme and style. It was fun to do.
