Great animation, good art, no story.
Excellent art and animation. Your 300-style blood effects were very nice, though immediately recognizable. I'll say that the art was a bit inconsistent in regards to style, so defining your own look might be something to work on that would really push things forward.
Your biggest weakness, I would say, was story. Nothing really interesting happened here, and I found myself bored. Why did he have to go there? Why did they wait a week to kill him? What was anyone in this fighting for? You really didn't have much of a plot, and with art and animation as solid as you've got I feel like you shouldn't skip out on good story telling. Doing that cheapens your ability, and you have a lot of talent. Take some appreciation of literature classes, read a few books on writing, and listen to the commentary in movies. Great work so far!
