yeah, the are really good, love photorealism.
My uncle used to nly draw in bic biro and his stuff was so detailed, a little twisted as he was a raging alcoholic and pill taker but the layers and layers of detail and work in to stuff a few inches across was mindblowing.
I once asked him for a picture of Knightrider, I was 10, he gave me a semi finished picture when I was 15 on the back of a bit of wall paper lol!!
