I came for the gorgeous art and stayed for the music love Owl City, love the remix you linked.
I know the focus is on the dragon, but that background
--how did you do such gorgeous clouds and nebulae? And that starry sky and the shooting stars adfghbvs
And then the dragon hovering serenely--you can just feel
the tranquility--I feel calmer just looking at her.
The combo of cell shading with a realistic background is interesting too--I wouldn't have made that design choice, but it's solid because the eye consistently travels back to Bluebell's head and shoulders, where the shading has blocked in the lighting. You end up focused on the expression, and the expression carries the whole feel of the piece. Very nice.
