The shading on the satellite dishes make look like the sunlight is coming from the lower right, or that the dishes are convex. I'd move the light circular area down a bit and dither the left side.
The old effect in the buildings and the grass are really nice. Color varition in the buildings and tank could be better, but that's a personal opinion. Good job on this, just improve the shadows and you are done.
Indeed, its greatly improved. The shadows are still quite off. The people/tanks/rocks needs shadows. Some shadows are missing like the dish on the right bldg. and the two on the right are missing in-bldg shadows too. If you decide to update, don't re-submit as new "edit details" in your profile page with new version :)
a significant improvement over the old; its suprising what a bit of detailing can do for a piece. still though im confused about the shadows on the ground?
