Design virtual band cartoon characters

I'm an indie musician. I'm producing several songs and planned to publish them under a virtual band titled "The Sweet Lemons". This project requires an artist (you) to design 4 cartoon band members(2D whole body), 4 pictures illustrating them jamming with their instruments (one of the pictures will be used as CD Cover). The cartoon should look stylish.(something close to the famous virtual band "Gorillaz" would be good, but not necessary to copy the style.) You could put in a little bit sci-fi element in the design. I've already got some ideas in the characters. We'll discuss the details before starting the project.
