Incredible effort
I'm a 3D artist for Unreal and Source. That means I understand exactly how much effort was involved in building the character models, their rigging, their animation, the sound, the effects, the particles - all the elements to this movie.
While it has its flaws; mainly the inevitable 'floatiness' or apparent reduction in gravity, and no real sense of power to the blows, that's ignorable out of sheer astonishment at this video.
I mean, LOOK AT IT.
What a sterling, 10/10 effort.
There are times when the lighting isn't very effective, and the scenes can be a little grating - Gooseman's for example felt a little cheesy and out of character - but these are nitpicks that you as an artist will overcome through experience.
The varied endings, subtle interactivity, and sheer quantity of quality work will overcome any basic criticisms. While it wants refinement, that's because of the work, not the compression. I am confident you will achieve it.
And if this reads as gushing, good. That's what I wanted.
