Another nice entry yay! I like the colors a lot...I agree with the comments on the gemstones though...If you need any gemstones modelled, I have a bunch that I've already done...But I don't know if that would be considered cheating...hehehe, never considered that.

I also think the gold roads don't look as gold as it should...I think its probably like a rippled effect? maybe you should change it to more of a polished gold to get the effect across better.
