keith moon was the drummer for a band called The Who, he painted his rolls royce lilac, by hand.
How do you make these???
Well I'd start off with and eaier project first All these wild colors and getting any pattern to match up would be a nightmare.
Start off with taking a look at the tutorial post else where and then pick a design thats no so complacted and start slowly with Photshop if youve got it and then progress your skins as your skill level progresses.
