Overall well animated, my kudos for your progress!
Perfect sound choice in my eyes (or... ears, to be correct) and an interesting storyline, though it is a tad bit emo, but not too much.
Since this is obviously one part of a longer story, I would like to see a prequel (what or who is this heartless demon? why is he chasing the boy?) and also a sequel (why is the girl saving the boy? Where does she bring him to? what will happen next?) .
hahahaha yes, I will continue with the story, and well.. yes some people will see this a little bit emo but this is like.. gotic, that is almost the same xd but Im not a emo hahahaha tankyou for the coment :)
I'm clueless...So I'll rate it on the animation.
A bit choppy, but like you said, your getting better. Maybe you should try to expand your plot an add in like, a prologue in the beginning. You get a 3.5/5, or a 7/10. Good show.
