Good animation, pretty good line work, and pleasant coloring. Backgrounds were pretty good as well. The biggest thing this video has going for it though is probably the point it is trying to make, because it is so true.
The issues I had though... the audio. It was fuzzy when it got loud. This was probably because the quality of it was somewhat low when you published it, but I don't know for sure. Also, your voice acting... I like it, but when you yelled "nooo" it sounded kinda quiet, like the character wasn't really yelling. Another problem I had was the choice of some of the sound effects, like when he was walking and then when he fell on the ground, it was like a distorted, amplified BUFDM, I don't know, it just didn't match very well to me.
But overall, it was enjoyable and I liked it. Here's my little review breakdown thingy I like to do...
+Pretty nice frame-by-frame animation
+Cleanly-outlined, colorful art
+True point the cartoon is trying to make
-Not very good audio
-Short
