Extreme exhaustion sometimes leads to creativity. In this case, I found a wierd shapeless doodle already on my paper. I don't recall putting it there, but then again I am having trouble recalling lunch right now.
I worked it up and it became this sexy if slighty underfed fellow. I wanted to draw something less buff than I usually do. He seemed to me to be a scamp, and a scruffy mutt.
"Barton" came to me as a good scruffy mutt name.
