The animation was not very good so you lose 2.5 stars.
The sound was... strange but you have one so that good. They are not emotion in the voice. For those two thing I remove .5
I can skip the start but is to long... very to long. It should be around 10 sec. If we skip the start your video is to short. The character are badly draw. Try do make more detail on them like some shadow under some equip or some texture and try to not hide the fight with black screens. Draw them will add some good element in your project.The voice you use is without emotion. Try to add some sound like the character expiry or add some volume. Start to speak slowly and when the character get angry make him speak faster. Change those think and your video will be better.
