Here's an artist with whom I was not familiar until today: Frans Mensink.
He hasn't done any catfight art that I'm aware of, but I'm really impressed with his style and with what he accomplishes using Photoshop as his medium. (I have tried and tried to make Pshop work for me, but I never seem to get what I want, and I certainly don't get the results I can achieve with Painter.)
His website: Frans Mensink Erotic Portfolio
And his deviantART page: Frans Mensink on deviantART
As for my own situation, I have no news. Tiredness is still my biggest issue, with nausea running a distant second. (I could also mention that my libido, which is certainly a driving force in my art, is basically nonexistent right now. That may be temporary, or it may be permanent. It's too soon to say.)
