@epoxy, the finished game would have a lot extra in the foreground similar to the detail of the ground. No detail in the ground actually looks a little worse in my opinion. The characters themselves are even 2-toned though though not as "rough" as the ground, so the ground looks to be more detailed.

Thanks for the comments!

The buildings are faintly-visible, but I like them that way; they don't distract from the foreground. In fact I almost think the ground could be less detailed. (I know 'less' is almost never good idea, but...) The rest of the scene looks good with flat colors & outlines while the ground is the only thing with internal shading.

I want to see this animated ^^

 Thanks guys, as for the buildings, maybe try adjusting your monitor? The are pretty defined on my screen, as well as my iPod Touch. :)

 maybe make the buildings in the background darker? they look cool but are too hard to see

 :D awesome

Love the style.

 Really great
