The old guy was funny,
But my personal opinion is that I think that some people rely to much on another animators style. The art here was defiantly a Cyanide and Happiness clone. Everything was pretty much alike. It kind of bothers me because I'm really picky when it comes to originality. My suggestion is that I think you should try making your characters in more of your own style. Anyway, that is my suggestion.
I totally laughed when I saw the old man's expression. Your sense of humor is something you should defiantly keep. Don't give up, and keep working at it! :)
Overall: 6/10 3/5
