ON THE SUBJECT OF ART, do you know about Picrew? Dreamwidth as a whole is FULL of incredibly talented artists who you should absolutely commission if possible, but in the meantime I like finding a picrew that lets me change the character's expression and then cropping a bunch of those for icons. You can see an example here; I think Novvy's account has some picrew icons too. (I've also used the phone app Custom Cast to create a character and then pose them with different expressions for 3D icons.)

I will do some thinking about the most fun ways to have Yvette and Jeannette interact!
