Your work is excellent. I feel like I am at the same skill level as the early humans and cave wall paintings. You have a gift and I am envious.
Not to derail the thread but;
Jeff, cave paintings are highly underrated for the actual art & symbolism involved in them, &, when you think of the tools available to them, the skills of some of the artists are incredible (like all artists their skill levels vary). I have several books on the subject but, if you can find a copy these days, a book called
The Creative Explosion is a very good read on the subject (can't remember the author, sorry - it's at home & I'm here).
