Is this getting a good score because it's anime?
To be perfectly honest with you, the animation itself is quite bad. I think the only reason this is getting a good score is because it's anime.
I believe you're a good artist, so i'll take some time to give a couple suggestions that would really improve your animations:
-The biggest improvement you could make is using more frame by frame animation. This will definately improve the overall look of your animation.
-Unless you're a really big fan of anime, try using a more unique style of drawing to make it more original and ultimately more interesting.
-If you can, try developing a deeper plot.
Other than that, I can see potential. You're camera angles especially are very good. Hope to see more work from you!
Peace
