Have you thought of maybe bringing your own style into the images rather then tracing over the photos?
thank's to all, iam still learning how to make cartoon from photo with full colour and with shadow. so the very end result is cartoon full colour but still same with the original image. mew24: actually iam not good in drawing smething like character or etc, but i like editing, like edit image/photo to smething different from original but still use the original object. thank's for the advice
