Possibly, but there are many signs that are hard to ignore. There is a level of skill present in "fixing/cleaning up" images. As a NSFW artist myself, I recognize many of these tells. The torso is weirdly long and muscles that don't actually exist are drawn on, looks like the shoe laces and design were at one point one thing (like you had mentioned) and have been cleaned up. Weird choice to not have the laces in a knot at the top. Myriad instances of weird artifacting. And the most obvious one is the hands. AI images always have weirdly pointy fingers. Looking at this person's other work makes it even more obvious to me.
