A while back, I participated in a project to design an album cover for a guy who records under the name Earmint. The project was really cool and a lot of fun to do. It started with a simple line drawing portrait of the guy. He then sent this to a number of different artists with the direction to "Do as you please." The results are very cool and it's fun to see everyone's different styles and interpretations.
You can see my final cover design, as well as see the other participants' pieces and download the album (called "Gallery") for FREE(!) here:
