Oh, now.. this one is kind of fun... I like it actually.
I would only suggest, clean up the lines so they aren't so jagged in places, but I think the design is good. if its not already big, I would concider re-doing the image on a large canvas. and placing it just so it is prominent in the painting.
May your world be painted in the
Brightest of colors!
