A scene from 'Thud' that always captured my attention:

'Upstairs, in what had been up until then the cash office, Young Sam slept peacefully in a makeshift bed. One day, Vimes hoped, he would be able to tell him that on one special night he'd been guarded by four troll watchmen. They'd been off duty but volunteered to come in for this, and were just *itching* for some dwarfs to try anything. Sam hoped the boy would be impressed; the most other kids could hope for was angels.'

I'm very happy with the coloring on the trolls. I went a little crazy with the texturizer in Photoshop, but they came out looking very rocky and story, so it's all good!
