I was impressed by the opening shot though the lense flair put me off a bit. However the lense flair in the second shot was utterly gratuitous and detracted from the otherwise decent composition of the scene. I like your art style and the backgrounds too, are they 3d models? You managed to blend their complexity and the simplicity of the character designs effictively and it gave the animation a recognizable style that fits the animations theme too.
I thought the voice acting, music and sound design were all well done and sounded proffesional. The animation too is good, though at certain points it really seemed you were cutting corners ie. 2:23 when she changes the direction of her run AND the jump at 2:48.
This is the first in the series i've watched so i can't comment much on the story but this episode was engaging enough to have me go look at the previous episodes now. Definitely some fine work!
wow this reminds me of naruto.
