Awesome start... got bad towards the end..
In the begining of the movie when they were getting ready to fight... THAT WAS AWESOME.
But towards the end it kinda lost its action, maybe the artist started to lose interest in making it or something.
Also, I have no freakin' clue who's side they are all on. What's with all the dragons n' stuff? Whats so important about the princes(Abilities, roles, appearances)? Try to clear up why they are fighting and why the rebels are called rebels. (What are the rebelling against?)
Overall- pretty damn good, nice effort (I loved the voice inclusions... kinda missed out on those in the 1st and 2nd), graphics are awesome(more Swift3d mechas would be kool), sound (No problem there) storyline(Im confused.)
Nail signin' off
Good Job
