I like it!
I really like your visual style in this, and the animation was incredibly smooth. If this is your first flash over 1 minute then your future work will be very tidy indeed.
There's room for improvement:- at times it looked a little scrappy; I didn't quite like how the bad guy blinds out, and the sword looked a little lame next to the rest of the visuals. I also had to watch it twice to realise what was going on plot-wise.
Definitely a series I'll continue watching.
