Much improved.  Shadows still need to be darker, IMO.  I like the flaky
texture of the pump.  Have you considered using a slope map, so that the
bottoms are rustier than the top segments?  I've had some good luck with
making good rust that way (my IRTC entry uses rust a lot, but the details
are too fine to see.  I can post an example if you like of a detail shot)
This assumes you're using Mega, but from your radiosity (Is it radiosity?),
it certainly looks that way.

The problem with the trees seems to be related to the sun (light source)
being directly overhead, or nearly.  Maybe moving it in towards the camera,
so that things are shadowed behind themselves (I recommend at least 10
degrees off, though, either left or right.  Directly in line with the camera
has its own problems) will help. Otherwise, all the leaves are in shadow and
so you only see their ambient color, resulting in flatness.
