What can I say...
Since you will be working only on the goku movies for now, I'll review this movie based on things you can improve in the serie.
First of all, some things to make you happy: I've got some nice effects and sounds (for the use in a sprite fight), the music was good, you used well the few sprites of hitsugaya bankai and you changed to different battlefields a couple of times.
I'm also glad that when you zoomed the sprites, it was for only a little time. I addmit that I hate with no good reason the zoom of sprites, but I liked the effect you did with it.
Another point is that in a lot of times the momevent of the characters had only like 2 sprites of animation. You need to put a sprite between then to make a smoother visualisation.
The battle was too predictable (special attacks, sword fights, bankai...) ...yeah, I know it's a sprite fight and you ran out of ideas...but an interference of the scenario, a dramatic scene (maybe...), a comedy moment, anything would make it nicer.
And there was only two moments that the sounds were too low/loud, but I know you will regulate the sounds next time (I just don't want you to forget).
I know you just do it for fun and just for the people who love these movies, however, I still think that you can be in a level above. I think that you have pottential. Just try harder and if you make a movie that gets a lot of attention (and/or even get a daily 1º, of course), you will see that you can be a better and more famous animator than you ever imagined (even with sprites)...but that's just me.
Anyway, I'm sorry for the topic change...good luck with your future projects.
