@skicoak, Thanks a lot for checking out my comic, I'm glad you are enjoying it!
The art has indeed become more elaborated. Part of it, as you mention, is about the story setting, but it's also because I originally envisioned the webcomic as a way to promote the character, in preparation for a Mayor Montenegro graphic novel I've been working on and off on for the last couple years. So at first I had decided to do the webcomic on a simplified style that could be done quickly so I could keep working on the novel. However, the webcomic soon took a life of its own and has since become my main focus. And I can't resist drawing putting more details, including the hatching. I think it helps convey the overall mood. I'm glad you appreciate it!
