Concept Samurai Kolab finished

This pic came out WAY better than I thought. 's line art is amazing. When I saw it I KNEW I had to do something with it. I picked this one. Holy crap. Anyway, job well done, no? I liked the sketchy look, so I left most of the lines there... Makes him look roughed up a lot. Anyway, I might go back later and fix it. Any suggestions for a bg?
