Very nice work! I wish you were local to me.
Hope it's okay to share some my toys here, this is a Jack based AR I built recently, it was a Christmas present from me to me because I love me. Built it pretty much to be a host for a Franklin Armory binary trigger.
Local guy did the Cerakote job, pretty happy with it.

The binary trigger in action:

Sadly, I have zero artistic talent. I can repair most firearms although I try to avoid H & R and other old, small caliber revolvers and Russian over and under shotguns. I can restore/refinish/repair most wood stocks. I can rustblue, Duracoat or Cerakote a firearm. An old Winchester rifle I'm restoring now is getting the steel blued, the stock refinished and the alloy receiver Duracoated. But, to do that skull is far beyond me. My drawing skills never got past 3rd grade level which makes me all the more appreciative of that kind of work. Of course, having it done on that receiver is what makes it!
