For my first-ever cartography/Photoshop project I'm attempting to replicate Torstan's Dragon Lair, based on his NewbieDM guest tutorial. Most of my maps will likely be battle maps, based on my group's style, so I thought this would be a good starter. Here's what I have so far. (Done with PS & mouse).

I had some trouble nailing down the wall shadows, especially in the sacrificial chamber around the steps. My current difficulty is figuring out how to do believable snow, as the tutorial says to use a brush with a gradient, which I'm not sure Photoshop can do(?). Anyway, it's been a blast so far and I would love any comments/critiques!

(And thanks, Torstan, for the tutorial!)
