Hi, I am a pixel-padawan, trying to create a mockup with improved graphics of an old Amiga game.

(1st try)
My inspiration:
http://www.wayofthepixel.net/pixelation/index.php?topic=3696.0 I used some kind of isometric projection, I guess. Although the geometry looks ok for me, it seems quite boring. Where do I add more colors? Or do I have to put some details in the walls to pimp it up? C&C are welcome.
