Hmmm..
There were parts in the video that were significantly better than others. The drawing is great at most parts, but for some of the fighting, the animation could be better, like, you added unnecessary frames at certain points, and if you removed them the hit impact could look even faster/harder. The one other thing I'd change is the music.. I like that type of music, it's just that I've heard better for that type I guess. And I could kinda think of some songs that are probably more suited and would be more epic for it.
Anyways, I remember watching the trailer for this way back in the day, and I was totally amped to see it, and I was so disappointed it never came out. Kudos to you for finishing it. Just seems like the standards for animations these days are higher than they were way back then. All the work you put into it shows though. So great job.
