You know, the self loathing irony thing is getting annoying in comics these days.
Yeah, sure our comic is bad, but we acknowledge it's bad, therefore it's funny! Well, that tired pony has ran it's last race. Shot. Killed.
Seriously, try making something with a least a tiny bit of artistic credential. Try colour perhaps, or even hand drawing them on paper and digitizing them later, no one wants to read a filthy, poorly done, hard to look at mess. I can tell you this, you fix some of those surface problems, and your comic won't get as much negative feedback.
