Hoo boy, this was an experience to sculpt. I was invited to do a ZBrush stream by  Draco-rex, and  MattMacroPika asked me to do a sculpt of his character, Matt. I agreed, and later learned that he wanted me to try my hand at doing some hyper muscle. Having just gotten the hang of regular anatomy, I hesitantly obliged, and after hours of hacking away at it, this is what I managed to create! This is the first model I've made where I was able to cannibalize parts of a previous one to save time; in this case, I was able to use the body of this model as a starting point, and then (almost literally) ballooned all the muscles out from there.

It took a while, but it was nice to get immediate feedback from both Matt and the others watching the stream, so I think I'll be streaming these requests more often. I also might have to start making sculpts like these commission-only, as it took quite a lot out of me.
