Very impressive
4/5
I was very impressed by the quality of the animation. Excellent work, and true to the characters. I especially liked that the characters were all a little on the short side, much like their 8-bit counterparts. The effects work was also nicely done without being overly flashy.
I wasn't a big fan of the music you chose, it was a little too light and took away from the intensity of the animation. Mega Man games have a lot of great, intense, pulse-pounding themes you could use - I would try using something else. Also, sound effects would have been nice but I think you were going for a opening credits-like feel so it wasn't a big loss.
But still, a near-perfect animation. Hope this leads to something great in the future.
