The animation was really good, but a lot of the illustration, especially the background illustration, was pretty questionable. Even then, some of the lines were shaky. Also, Luna's thighs were HUGE. Like Disproportionate huge.
My guess is that this was supposed to be a sort of sci-fi/space themed Avatar. And I imagine you aren't intending to continue it because story-wise, you play it pretty safe here. The characters are well-established archetypes, and the plot doesn't have much potential.
HOWEVER, the action was excellent. And if your goal was to demonstrate your animation skills through badass superpowered action, you succeeded gloriously. In fact I noticed the art improving the moment the characters started fighting. I imagine a lot of work went into these sequences, because they have pretty high FPS.
Good luck on your grade.
