Right, the movie was entertaining to watch, but without sound it damages the score really.
The effects and attacks are well done but without sound effects it's boring and doesn't add the intensity to the fight.
The characters, even though creative hybrids, are sprites, and sprites that don't animate, hand drawn creatures with some animation would of made this better, the backgrounds too are copy and paste stock footage which is disappointing.
Things to improve upon:
Sound is needed
Detail and animation skills for characters
Handrawn or creative backgrounds instead of stock pictures.
I really do like the Attack effects though.
