Game poster - Feedback please!

I thing I would add some kind of gradient to the track close to their feet to imply that the sun is not hitting it at the same angle as it's hitting the steep part.

And just because it's 3d doesn't mean that the nose and claws shouldn't be clossy and have speculars. An exemple of excelent texture on a 3d poster is Surf's up (with some Paul Lasaine work, look him up!)
