I think Hyperpotamus [tapastic.com/series/Hyperpotamus-And-Stick-In-The-] is a great series that should be getting better noticed. It's a very comical series where a hippo and a stick do unlikely things together. Trust me, the jokes are typical.
Smilemore[tapastic.com/series/smilemore] is another comical series. I like it because of the comedy and very colorful art style.
Peter Deadle[tapastic.com/series/Peter-Deadle] shows the life of a pitiful reaper called Peter that would rather play Zelda than kill anyone. Very funny.
Lastly, My series! The Preney Life:
This is a series showing the life of a Furry Blue Lizard living the life of his author's most funniest parts of his day. But when Preney experiences it, the comedy gets highly exaggerated. The comic revolves around the subjects for nerds: Video Game addiction, College life struggles, and Anime stupidity
