I love this!
First off, the animation, for once on NG, was actually quite good! Nice timings and stuff. Of course your stretch+squash was little amateurish, but all things considered, this was great!
Secondly, I really dug how you mixed up the angles, and did close-ups and longshots and such. The final shot was brilliant, as it zooms out rotating. A little cliche, sure, but really well excecuted.
I do have some qualms with the choice of starting with backgrounds then suddenly moving to white. I wish it was consitent one way or the other, though if you stuck with the white, I might recommend splashing in some minimalist little environmental images. Some rocks, bits of grass, and shadows coming from the warriors, to be sure. Just little pieces to make it feel complete.
Overall great attempt though, and highly entertaining. Alot better than thigns that have scored 4.00 and higher even, so be proud and keep at it. I see you going places in the future!
