Actually, I have one more thing I wanted to say about that critique you linked to.. "Comics could be good", was it?
IMO, despite his attempt at a "hard nosed" review, I thought his comments about your sequential and story telling ability was the highest praise a critic could of comic book creators could give.
I mean, just about anyone could develop art itself with time and practice. But composition and story telling skills... Now, that's something a lot harder to develop...
If it was my work, and this early into it, I'd be pretty proud.
