pretty good man!
Hey, congratulations on your first short man. Its actually too good for a first timer, you know how to handle timing, sounds, voices and of course 3D really well; you have a firm grasp on scene composition and you know your deal about anime style. On the other hand i find your basic animation and drawing skills way underdeveloped, but hey, still awesome.
Regarding your spanish subs, they are way off, my guess is that you used one of those translator programs which are far from accurate, smart move though.
im in fact spanish, just send me an mp or whatever if you want help with that
