A Journey To Earth was quite good - I liked it. Rest was a bit average to be blunt. But focus on the positive - you're not "missing a chromosome", you "have a lot more than a chimpanzee!"
What you want to do if you want people to find your comics really funny is to go off and get an idea (from anywhere - politics, films, crazy things that happened to you on absinthe, etc)and then script your strips - write down ideas first, then make the strips.
Other than that, good start fella.
