Might be generic anime, might not be.
Your style, while not poor, is very common. You might want to consider developing a more personal, varied style to separate yourself from the hordes of weeaboo bullshit that plague this website. In the gunfight scene, your character appears to be off-model several times, but considering that you are alone in composing difficult FBF animation I suppose it's understandable. Despite this, the art has a sense of consummate professionalism about it; if not marred by terminal overuse of photoshop textures.
The biggest problem with this trailer is its lousy exhibition. It is not prudent to call the scientest "crazy" or to call the toys "evil." Those adjectives are judgment calls the audience has to make. You could probably just get rid of those without to much damage to the overall trailer.
The music and sound quality are both good and I appreciated a minimum amount of garbling on the part of the voice actor playing the scientest. The music, while appropriate, was not very interesting.
The best thing about this trailer was its dynamic editing, which, judging by your other movies, you have a natural talent for.
The thing that would do this in is complete and utter adherence to the cliches of bad anime, which this trailer dangerously approaches at times. Over-dramitization, simplistic plots, girl robot-on-guy robot action are all things that can be easily avoided and would probably enrich this movie.
