James Jean
Alright, If you want to check out more of James Jeans work I recommend the following:
Process Recess
This is his blog, where he posts images of projects he is working on and sometimes comments briefly on his process. Prepare yourself to lose an hour or two going through the blog archive.
This site also has his store where you can buy his book, prints of various projects, and if you have a ton of extra cash you can buy some of his original art.
This is his online portfolio. Shows all his published work, as well as a lot of unpublished stuff from his sketchbooks.
This site is basically an illustrated story/conversation going back and fourth between James, and Kenichi Hoshine. It hasn't been updated in a long while, but it's got some really interesting stuff.
enjoy.
