Anyway:



1. Quit using layer 4 eyecandy in the background, especially if you use the same tiles in layer 4 later on. More of a nitpicking thing but still it can throw off perspective easily.

2. See that line? Every ground tile above it is one tile, and every ground tile below it is a different one, only exception being the gems. That's ugly. Fix that.

3. Throw in some gems. This is Diamondus. Gems. PUNCH EM
