Man can that Skottie Young draw. I'm surprised really that it took me so long to actually find him. I was just in the library getting a few graphic novels with my son where this book immediately leapt out at me.
I ended up renting it (and re-renting it) several times and was really fascinated by his process. He clearly uses the same sort of tools I naturally gravitate towards... the pentel brush pens and micron fine liners. But he gets some wonderful expressive lines from the brush pen. So there was nothing else for it but to do some studies!
It was a great little exercise and I'm really thinking that these would look great on Jack's wall so that might be the next step... get his room decorated in a Skottie Young way.
