Hey sorry for the wait, I've been fighting a headache and I've been trying to focus enough to reply but it's been a bit troublesome oof.
I didn't see any characters I'd use unfortunately. However, I really do love your art and I love the style of the "character scenes" options. Would you be okay with drawing a character like the one below in a library scene? They're a Draenai / Human hybrid Priest (World of Warcraft) and can usually be found in a library, sitting on a window ledge and reading. As a side note they're much shorter than most Draenai are (they're only 5'0") so they'd fit a window rather well. If you have any questions please let me know. :3
