I've noticed that in a lot of your cartoons you don't have much of a story and they are paced excruciatingly too slow. Also the main character is just hard to look at and is not very interesting.
I suggest you make a storyboard before you start animating. The most important part to any story is giving the main character a goal, and to add problems and stop him/her from reaching it.
Also if you want to keep the same main character I suggest you make another character with more personality.
Also most of his adventures are just feature him doing boring everyday task like eating, being on the computer, talking on a phone. Make your cartoon more exciting or dramatic or funny.
Come on now it's a cartoon! Unleash your imagination, anything can happen in a cartoon.
