One of the best artists dabbling in "Femuscle" is Chris Morisson (AKA
); his simple, minimalistic style makes what are arguably freaks of nature seem very natural and - if you are of the appropriate mindset - very appealing.
The above is fanart of Dr. Otto and his wife - the amazing Andrah, the sweetest, sexiest non-violent killing machine the universe has ever seen. They seem to be doing a Star Wars cosplay - no particular reason; do you really need a reason to do a metal-bikini-Leia scene?
I referenced several of chris's drawings for the style and layout - colors are all me.
