Gluteus maximus feed back

I’ll be looking for feed back for more than just this. I recently changed it for reference images I have.

Here I changed it again.

Looks pretty darn good. Can’t think of much to say. Maybe a little more fat on top half. And it looks very firm again instead of like a big ball of fat affected by gravity.

Maybe define the lanmarks such as the greater trochanter, PSIS and sacral triangle a bit more?
