It is a really small image to try and work with but, some quick edits using ACR, Photoshop and Topaz;
How much of the editing did you perform in the color image and how much when you were in the b&w image?
I started in ACR with the color image and used the gradient tool on the sky to help define the clouds (Added blue, reduced the Exposure, Contrast, and added Clarity).
I then opened the image in Photoshop, while still in color I dragged guidelines out from the rulers to define a crop, cropped the photo and then on a duplicate background layer I used the Topaz Adjust plug-in's Clarity preset. I then clicked on Edit and faded the Topaz adjustment to 75%.
Once that was done, I made a B&W adjustment layer and played with the blue, red, yellow, green, and cyan color sliders to get the contrast I wanted, paying close attention to the blue, green, and cyan.
I had already made 2 new layers, one for dodging (soft light) and one for burning (hard light). A dodge here, a burn there with the B&W layer above the color so only the B&W was seen.
I then used the Spot Healing Brush Tool with Content-Aware selected to get rid of the hoses, cables, (whatever they were) and ties laying about. It took a few clicks of the Clone Tool to clean up the Spot Healing Brush artifacts left because it was such a small image.
Then I added a thin black border and was done. The editing from start to finish probably took 60-80 seconds.
I
always start in ACR. Then when I move to Photoshop, my opening sequence is to duplicate the background layer (Ctrl-J), make a New Layer, (Shft-Cntrl-N) Blending Mode - Soft Light and fill with 50% gray(for Dodging) and make another New Layer, (Shft-Cntrl-N) Blending Mode - Hard Light and fill with 50% gray(for Burning) .
While I am evaluating and editing an image in ACR, I work out a basic plan in my head for what I want to do in Photoshop, so once I get the photo open in the Photoshop workspace it goes pretty fast.
I have the image on a 22" calibrated monitor and all my work pallets on a 19" dual monitor. I use a Wacom Intuos 4 Medium pen tablet to do the editing, except when I need to type in text.
Here is a photo of my image editing workstation. There is an image open here in ACR on the 22" monitor. I keep my work pallets on the 19" monitor minimized when they are not in use:
