You've got some that are good, but it looks like you're falling into the n00b-trap of throwing out as many comics at a time as you can and hoping some of them hit the target.
The advice I have here is to slow down. Before you hit the button, read over the comic a time or two. Is it at least as funny in print as it was in your head? If yes, post it. If not, scrap the idea or try and alter it so that it is. I will say that if you're trying to make US laugh, go browse the toprated lists and see what tickles our collective funny bones.
One more thing to keep in mind: Unless you're trying to separate different series, keep to this thread and don't create new ones. Flooding the forum with a new topic for every new comic tends to raise the ire of the voting regulars who come through to peruse aspiring newbies.
