Just read through City of Blank, and I like the premise and setting so far. And thanks-- I'd be happy to draw one of your characters for you.
But if you don't mind, I think I'd rather draw your main character ("Rexerse", right?). Because, while I do draw cute characters now and then, I like to draw other things, too. Though I suppose I may have earned such a reputation, since the manliest character in my current story is a woman.
I do like Lys's design, though. The slightly eerie-looking mask is a really nice contrast to her otherwise cutesy appearance (ribbon, frilly dress, small frame, etc).
I'll probably do this one tomorrow, as I just finished today's pic.
