Here are some tips of my own for a webcomic. Considering my artistic ability is nil, maybe it's not my place to critique drawings, but I do know a thing or two about writing, so I thought I'd throw my 2 cents out there. Of course, you're a very talented guy, Faw and probably don't need these tips, but here you go anyway.

1) Don't include an omnipotent author character. You'd be surprised at how many comics incorporate this, and I'm not just talking about sprite comics.

2) Keep the characters in character. If your characters are generic, or just foils in random gags, nobody's going to form a connection with them and that drags down the quality.

3) While it may be a good idea to keep the writing of specific incidents spontaneous, try to keep a general idea of where you're going, so you don't write yourself into a corner.

Probably incredibly obvious advice, but there you go anyway.
