Even starting right at the top of his head, JC has had some adjustments made to him for the revised "Shit Got Real" version. As you can see in the comparison images, the original JC has flatter hair and a smaller beard. The revised JC completely makes a new head mold and turns his hair and beard up to 11; a large spikey portion of his hair juts out, his bangs are longer over his right eye, and his beard is much longer. His "GODLIFE" tattoo is the same, but now there are more additional tattoo's. On the original JC, his hand bandages were part of his hand cast, but with the new JC, his arms and hands are wrapped up in actual bandages.
Overall it's a fantastic upgrade. The only "downsides" are that his costume is much more sparse on the revised figure; the original came with a track suit and a zombie head that fit into a satchel that hung around his waist. The revised JC looks more militant; more badass and more roughed up. Which was something that I was excited about. Even his feet changed dramatically; the original JC had sculpted shoes whereas the revised JC has faux-leather combat boots that his legs/feet slide into. It's really awesome.
I had been keeping an eye on JC through eBay, and when one came up at a good price, I jumped on it. I had a few "custom" ideas that I wanted to add; a weathered leather jacket that I picked up off eBay from a Mad Max: Fury Road unlicensed 12" figure, and a wood/metal sledgehammer that I also found via eBay. I just thought that this JC would look badass standing there holding a sledgehammer. Forget swords or guns - he needed something raw and blunt and heavy. The sledgehammer I found worked perfect. The great thing about 12" scale figures is all the amazing 1:6 scale accessories you can get for them.
