Here's the old strip, which somehow kinda worked without much definition in Hazel's face? But it looked weeeeird when flesh color was added, so I gave her a little cosmetic surgery with a Wacom pen.
I remember feeling like strip #500 had to be some kind of pivotal moment in the series, because I'd been drawn into Jeph's Questionable Content when he dropped an emotional bomb that started with strip #500, and read backwards from there.
This was barely a scrape compared to that literal bloodshed revealed in Faye's flashback arc, but it was fun "allowing" myself to start giving my characters more depth because, for some dumb reason, halfway to one thousand strips seemed like an important enough reason to start doing that. :)
