I just went to Ken Foster's blog to search for a match for the right picture and it is not online. I don't know what happened and as I have some of his works saved I decided to share the left one "Boy".
Remember that Ken's work is a journal so you have to click at the right picture if you want to read.
I hope his blog comes back soon for his work is amazing.
Update: 10/10/2011
Ken's blog is back.
