The one thing I don't get is how this mysterious dragon that lived "thousand years ago" that you dramatically introduced in the beginning could just be beaten by a single strike. You have to follow a straight line to make your movie authentic. The same applies to your special effects, on the one hand you are trying to make it serious and dramati, but on the other hand you are using weird dragon ball stuff, that rather makes it funny. You have to improve those points, if you want to be taken seriously by your viewers.
