I recently watched a video counting down the top 9th doctor moments. Good old Christopher Eccleston. I like the shading on the pants and jacket. Looks like he's being lit from the back.
Yeah, all I knew was I wanted to do something other than just a flat background so I just threw that white in on the edge. I wanted to make him look lit from behind but in theory it doesn't make sense with the screwdriver on the other side. I think I just wanted a better contrast with that dark side on the right.
