My main bother with this one was to work out what would happen if he was lit from two opposite sides by the lamps, one near, one a little further back... I quite enjoy problems like that!
Once I had established where I wanted the lamps, I washed grey tone over the paper to see the shape of the composition and the location of the various elements. I sometimes find this more useful than a pencil rough as it leaves all the specific marks for later whilst giving a very good guide to where stuff is going to go.
As with the first image I reached a point where I was happy with the picture aesthetically without it doing its intended job! I had wanted to have the central character surrounded by his captors.
To that end I added another figure in the foreground. The costumes of these guys are inspired by English mummers...
