This image was originally uploaded onto Twitter on November 2019, and yet gets so much right about the character down to the minute details like sharp teeth, pointy ears + earrings, curly horns, horizontal pupils (which some artists still omit by mistake), vaguely chinese inspired clothing. And all this from the barest of details (Toutetsu being a prideful, greedy taotie).
The area near her crotch aren't mounds of venus by the way, it's just creases on her shorts, seen on post #4899467.
is there a pool or tag for these taotie prediction art?
There really isn't that much art for Imaginary Toutetsu around to necessitate a tag or a pool. You could just search for her name + original, or just touhou + original.
