Extremely nice looking, though I would up the specular a little bit to add some highlighting to it.
Also, I realized, that there is a small issue with normal maps in general in spring. You must invert the Z axis to get correct lighting. This can easily be done by inverting the channel green channel in photoshop.
EDIT: Did you use WM to make the height map? If so, why not try baking some of the light map onto the texture? The select convexity combined with the lightmap offers excellent feature highlighting. If you used WM, could you please post the wm file?
