I wish the legs were a bit less toned, because that makes the rest of his bodies disproportional, since they are toned but the rest of the body doesn't follow through, making it weird. Check page 4 and 23. They clearly aren't designed as fat girls but everything above bust is just small... I don't know... I'm not an artist but that's just my 1 cent after fapping for the 5th time.
I'd recommend against that BBW tag. There's no fat there, the artist just draws 'em big. female:muscle is much better.
