Yeah, now that I think about it, I think you're right. Countless many webcomics have great new art and crappy old art.
But, I think that at least I should redo the really bad ones, like the one you linked, which has gotten a few complaints. And there are a choice few others that I think I'll do, just because I want to.
But ultimately, I think I don't have to go through the archive and redo the first 100 comics, which was kinda a lofty goal I had ^^;;
Instead, maybe once every couple of months I'll pick one in need of correction and redo it. Here are a few I think particularly need it:http://hazardswake.comicgenesis.com/d/20040414.html
(The dialog up top is real messy)http://hazardswake.comicgenesis.com/d/20040419.html
(Word bubbles in weird places)http://hazardswake.comicgenesis.com/d/20040421.html
(That mess of text boxes is damn confusing)http://hazardswake.comicgenesis.com/d/20040512.html
(Major tl;dr clustermess. Needs a bunch of extra frames)http://hazardswake.comicgenesis.com/d/20040528.html
(This one's also pretty tricky)http://hazardswake.comicgenesis.com/d/20040625.html
(This one's a "maybe")http://hazardswake.comicgenesis.com/d/20040818.html
(Sooooooo much teeeeeeeeeeext)http://hazardswake.comicgenesis.com/d/20041128.html
(This one's a maybe, just because FATIMA WITH HUGE HEAD in panel one looks so damn awful to me. You'll notice I didn't mention the three black and white ones before this, because they've grown on me and I think they look kinda cool ^^;; )http://hazardswake.comicgenesis.com/d/20041202.html
(Another maybe, because of text overflow)http://hazardswake.comicgenesis.com/d/20060725.html
(A third maybe, because of the text crammed into panel 2)http://hazardswake.comicgenesis.com/d/20060802.html
(And, of course, this one)
