I think that you stumbled upon the back caves at Lascaux, where the young guys hung out and did their graffitti thing and smoked funny antelope dung while their uncles and fathers did their serious cave paintings of the animals they revered/hunted/ate.
So, glad to see you here in this challenge...this is wonderful...I am hoping that you will add more of your "pictorial" steps so we can really see how this comes together...your work is amazing... really looking forward to more shots...
Oh goodie, more rock faces! Your vision and execution is fantastic, as with your whole series of these creations. I hope you plan on doing some kind of gallery show with the lot, they are quite wonderful!
