Nice work!
You could try to do the one that has the huge scorpion at the back.
That´s a good idea...I searched for it on the net but could not find it. The last comment I´ve seen was that it might have been a shirt custom made for him.
If you can find a clear picture of Larry's back with the scorpion on it, I could easily enlarge it and make it into a stencil for you to use.
