I noticed that too when light hits her abs in a certain angle. Looks just a bit too muscular
I didn't think her form looks "wrong" at all, her arms appear to be quite taught and reasonably muscular as well; thigh-line, etc. I'm only commenting subjectively about the concrete abs (plus, I really like the feather-light appearance of her poses there so I might have enjoyed some more of that soft touch elsewhere, eh). Your work is exceptional.
Mostly, there HAS been a fuckton of muscular abs this month; overall. Just a trend I thought out-loud is all, mate.
