here's the crop with adjustment layers added. i think ultimately i'll probably reduce the saturation a bit. i've gotten so i can't see it anymore.
i'm also not sure about the crop itself. at full size, the shadow of the tree falling on the building to the viewer's right that you can see a bit in this image adds more interest than you can see here.
ultimately, i'll probably do some cloning to increase interest on the right. right now, i need to get away from it for awhile and get some perspective.
