This is a piece of isometric pixel art I've done for a contest at
PixelPlaza.de. My username there is "Gama". You should maybe check that site out, if you are interested in isometric pixel art.

The scale is pretty small there, and the style is like "the more realistic it looks, the better". That's why I use a lot of textures and details.
It shows spook city from Michael Ende's Neverending Story. I didn't watch the film, it's based on the description of the book.
A Making-Of can be seen
