Listen, I'm gonna be honest.
You are what looks to me like an awesome cartoonist and animator (trust me, I only review the good guys). The only advice I can give is that you spend a little more time on your plot/jokes/ideas. I mean, I loved the way the characters were draw, how they were animated, etc. I just think it'd be fun for you if you maybe collaborated with one of your friends (let him write, and you animate).
What I'm saying is that I'm looking forward to your future animations, just with a little more extensive and thought out plot. Good luck, man! Keep up the great drawings.
