Hey Thanks for the compliment! I really appreciate it.
As an illustrator living in Montana, that woodcut style is very popular and I've used it to draw everything from cows to fishermen. Lots of fishermen. I just draw it in ink, scan and color it in Photoshop. I love the irony of using super high tech to make things look like they are really old.
If you like that line style, check out the work of Franklin Booth. He's the master.
