Nice work Dexter!
Phil, I like the treatment above.
Joe, nice images! I think if you're typically getting slight purplish color shift along the right edge, you might be able to minimize it for some images by pulling the purple hue slider to the left to shift the purple closer to blue. This will however affect other similar hues in the image, such as some blue skies, but I find it can be an effective quick fix.
As for the detail crop: seems like color moire mostly, though the second floor windows above the minivan are definitely off. My feeling from the few M files I've played with so far is the M tolerates more sharpening than the M9, so it might help to push the files a bit more. As well, for this type of scene, it might be beneficial to try f/11 or thereabouts where some diffraction might minimize the false details. With stronger conversion sharpening, you should still be able to pull off a good file.
