This is cool!
Last time there was not even a background and this one sure doesn't look so bad to me. I like that light reflection on sharptooth's skin.
One thing that might perhaps be improved in a future picture (and this is really only meant to make the good work even better, for I really like your work) is that those light reflections don't occur just on the parts of the sharptooth which would be exposed to the sunlight, but also under his chin, neck, and belly where a shadow would be more likely to occur than a light reflection.
But just for the record, I never ever even got as far with my MS Paint work to even include light reflections.
