.The ogre resistance encampment was an interesting challenge, here's one of many passes we took at it:

Moleskine sketch

Color rough

"Ogreifying" the location in photoshop

Establishing the scene as an ogre encampment and finishing in photoshop.

I prefer the previous image over this one, I'm a location guy more than a character painter but they asked me to populate the scene with characters. This is what I came up with.
