The main thing that bothers me is I don't know why this is all going on, if theres any reason at all. If its supposed to crazy and wacky then the bone chaser and the flying bone are very surreal but then the landscape isn't as crazy.
As for the technical qualities, the composition is too balanced I feel. And the bone chaser is right in the middle of the page, so we are missing out on the action of the chase. I also don't read the wings on the bone as wings immediately, rather more as a bow.
