I'm pretty sure all the tainted rusher busts are done by jaques00, who is a much better artist than adjatha could ever hope to be. Also, I'm pretty sure the end state of the rusher is meant to be kinda horrifying, she's a freakish chimera of damaged genes.
For an actual example of Adjatha's fucked up art, There's Johanna who's skin looks like plastic or something, not to mention the fucked up sizes of her lower body.
Then there's the nuka rancher, which I don't even know what the fuck
Adjatha used to be able to make normal looking art, but just stopped wanting to I guess.
