Here is my attempt.
I had to work with the low resolution version that EosD had uploaded so some of the adjustments have caused negative effects that would not be visible if I had been working on the original.
My vision was to remove some of the clutter and alter the lighting, something that may be advantageous to do on any photograph. I was aiming for more conventional rather than shock and to help the majority.
Steps taken.
Duplicated layer and then desaturated using channel mixer, favouring a bias towards the red to get the right contrast.
Added a second layer and then a gradient at the bottom from foreground to transparent. This was converted to colour and a dark green used. I then deleted the top of this and altered the layers opacity to get the balance I wanted. I was aiming for subtle here so it may not be that apparent in the final image.
Added another layer and did the same as above but for the top of the picture and used red as the colour. Again altered the blending to get my desired effect. At this point the sky was a lot less saturated as I was aiming for a soft light sunrise/sunset finish.
After altering the layer positions in my layers pallet I then used the history brush to remove some of my coloured graduated layers from over the building so that it kept its main colours and wasnt subject to a obvious red/green gradient.
Flattened the picture then painted over all the building work on the left of the picture with a flat colour similar to the sky (I chose the colour using the colour picker by selecting a area of sky very close to where I was working) and then used a basic brush to do this. This removed all the distraction on the left but left the sky with a big bland and none matching area that looked all wrong.
I then selected the healing brush and selected an area from the sky that I had not touched, this allowed me to use that texture and keep the colour basically the same. Using it at a low opacity I then painted my bland area and matched it to the rest of the sky.
At this point I addressed the composition by selecting a crop to lower the horizon and move the building approximately to the lower third. This is often more favourable and appealing to the viewer.
This altered my vision of the picture and I then decided I could increase the saturation of the sky to give it a bit more impact, I felt the picture could handle it. By using the red channel only and increasing it I got the level I was after without it impacting on the rest of the picture.
I then adjusted the contrast and levels using curves, added my basic border and uploaded.
Total time taken in PS approx 30 mins.all done on my laptop so the colours and brightness will not be spot on but should be close enough for this purpose.
