It's alright.
I like the art style. I love it when the shading is done in one color plus black. The movements were done pretty well. The storyline seemed non-existant though. All i know about this is that this guy with a sword kills some kind of creatures so he can get some wings. Then he gets his wings. But the art style makes up for it. The action wasn't too intense though. Sadly, the best action part was when he cut through the demon in slow motion and you saw the blood stretch out. Thats bad when that is the best part. You should work on making better action scenes, work on the storyline, and work on voices. It was annoying trying to pick out any action that I might have seen if i wasn't too buisy reading the subtitles.
