Some basic pointers

Here's some general advice on comics;

READABLE TEXT: Without readable text, your joke won’t exist. (Well, technically it will, but just as technically as a tree falling in the forest with no one to hear it) Take your time with text, do plain print, and use computer text if you can, unless your handwriting is superb. Also, be careful with those speech bubbles. Put them strategically, not willy-nilly.

BREAK THE MOLD: Or at least change it around a little. Straight man and off-the-wall guy is done a lot, but it doesn’t mean you can’t do it, it just means you have to change things around a little. Leader desperately tries to get his group to stop doing random stuff? Or group tries to get the leader not to lead them into the random stuff?

WORK ON THE ART: Yep, it's true: everyone can draw. (disclaimer: those with no hands may not find the above true) Some have more natural talent than others, but it's a matter of practice. You'll probably find that you can draw in cartoonish styles, but not realistic, or vice versa. If this happens and you really want to use that style, it'll take a lot of willpower from you to work extra hard to get up to par in that drawing style. Or, you can collaborate with a drawer.

PRACTICE: When you first start, chances are that your comics will be, um, not good. So start writing comics, write them often, and maybe show them to family or friends, until you feel secure enough with them to start making some for the world. The internet can be a harsh place, and you don't want to get caught unarmed.
