First, I gave you 2/5stars because its your first video, because for me its only a 1.0 stars.
Second, the animation is correct, but at the begining the guy don't move his legs, a little strange for a human to move only by going up and down. The graphic are bad and you know it ( I hope ), for the first video it's normal for me, if you want to continue, DO IT! because it's not by waiting that we become better at something. Anyway, the video is a little short, too short. Then make it longer, not 16 sec, 1 min will be good for the next time. And the sound, the explosion is good, but the window didn't make any sound and when the guy walked.
Third, continue working on your talent, because you'll maybe become a good one.

Eh, not too good. The only two reasons I didn't blam this is a) In the comments you ADMITTED you didn't think it would be that good, unlike certain noob video makers. and b) It's better animation than the video of previously said video makers.

lol comes back and someone is reading it normally. . .
