Thanks people! Here's another, again using Photoshop. I started from scratch on the compuar with this one, rather than draw it on paper first.
Poor little lost dragon sitting in some moonlight in a forest full of really annoying fairies (the lights in the trees). The water looks a bit strange in this one becuase I'm not used to drawing landscapes.
Terragen is a photorealistic 3D landscape generator that I use.
