I've never seen that film...
But surely i will after i saw this. It is animated in a very clean manner, the only imperfection i could take into your notice being the dragon's flying stance, that remained the same even when he was doing maneuvers: he should have moved his body, especially his back and his head, to get higher or closer to the ground, and such aerial movements.
Apart from that, wish you the best of luck with uni and hope you will keep up submitting your work here. :)
