You can give some kind of spark of life to a comic that a photograph doesn't really have. A photograph, even if it's connecting with you, it seems very dead on the page sometimes.
I have this certain vision of the way I want my comics to look; this sort of photographic realism, but with a certain abstraction that comics can give. It's kind of a fine line.
Writing a screenplay, I'm like, "All I'm responsible for is that final script, and I take great effort and pride in that." But once I give it to someone to make, I can disassociate with it entirely and not worry that my vision isn't being represented, because I understand fully that that's not how it works.
I just try to make comics for myself, try to give it some kind of unity throughout. That often involves tiny details. I'm never sure what's going to be obvious or what nobody will ever notice. I put stuff in my comics that I thought was blatantly obvious, and nobody noticed. And things that I think are buried in the background, everybody gets it. So I try to be consistently aware of every part of the frame.
