If you like Mitch OConnell or if you are into tatoos or illustration in general this is a great book. Tatoos have become pretty standard but these are a notch above the rest.
If I was being really picky, my only complaint would be that the line art is filled in with some shabby coloring. As if an intern who just learned to use a computer and gradients did the coloring. But I'm assuming it's to simulate the coloring in a real tatoo, so who really cares?
