Design virtual band cartoon characters plus 5 pictures

I'm an indie musician. I'm producing several songs and planned to publish them under a virtual band titled "The Sweet Lemons". Please browse the website for more information. [login to view URL] This project requires an artist (you) to design 4 cartoon band members, that means one 2D whole body picture for each of them, plus 5 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.) Please listen to the songs post on the website and see whether you can design characters that suit the style. I've already got some ideas in the characters. We'll discuss the details before starting the project. It'll be perfect if you can provide a very rough sketch of one character before I start choosing.
