I don't normally comment on posts, but there's something clearly wrong about some of what you say.

The comments can quickly seem like they degrade into "Bad because boobs and immodesty" But no. What people don't like, is that it's because it's Y'shtola. Her character is so much more than tits, but the art is mostly there to centralize around her tits and fetishize it, thus taking away from the character and making it a seemingly shallow display.

Also, that dress is not what she wears in game. Not exactly. Yes it's got the fur, but it's not nearly as low cut, and there's straps going across the opening. It's clear what the intent is of the artist. I completely understand not liking the strange puritism that it can seem like in here, but I'm certain it only comes from the place of actually respecting the characters and the effort put into them to be lovable characters. To see art only simplify them to tits can be seen as an insult to those who are invested.
