I really had few idea about the background, so please don't blame about it.
It's okay; sometimes having something can really make a difference.
But I like your (random) choice of a background--it feeds off the astral feeling that the sky produces as the T-rex is ice skating on two raptors; it's like a fantastical wonderland in the night. This atmosphere also gives in to the light, uplifting mood that everyone in the picture is being happy (although I don't know about the one in the mouth
) and enjoying the moment in magic.
Another thing I like to add is your lack of outline--which is true for creating realism that you normally don't see black outlines unless there is black present near the edges, light is missing, or for other purposes other than reality--and that's a good thing: it gives the sense of lighting a smoother texture and effect in the overall picture.
Overall, it's exceptionally well done.
About the anatomy, you're going to need to talk to someone else because I don't know about that nature...yet.
