Not sure what it is about the original photograph, but, doggone, do I like it! Must be that whole "country boy" thing.
A country boy that listens to country, metal, and rap and likes to play MMOs, RTSGs, and whatever Minecraft is, with that Southern drawl. Purr~ (Admittedly, it was a bit of a culture shock for me the first time I met him and he started going on about raiding with his level 80 shaman and looking forward to Cataclysm coming out in that really thick accent of his.)
Now if I was exceptionally talented (and patient) I would have detailed the texture for the jeans beyond the high contrast in the seams. I'm not quite there yet, but maybe someday.
Took about three hours. 0.5mm & 0.7mm pencil on 8.5"x11" plain paper. Photoshop for the blue.
