32x32, 125 tris? Oh, sweet! I agree with Hawken, why don't you show us wireframes? ^^ PS: NathanA, I would suggest to add some fake shadows in the scenery, I'm sure they will add a better visual touch. Unless you already planned to add them!
Kawe: 256x256 is fine, but the details could do with some sharpening, maybe add more detailing. You should also clean up the seams, add some weathering maybe.
