Clone tool to "grow" water where glasses were. Played with lighting and focus. Then, applied concrete texture over wall area and used free transform/perspective to grow it to cover the foreground (shown here before pulling to cover whole foreground).
Separated out the water from the sky, gave the sky a hue/saturation adjustment (darkening and mostly desaturating), and gave another hue/saturation layer to the water, giving it a blue hue. Lastly here, gave another hue/saturation adjustment layer to the concrete foreground, darkening it, lowering saturation.
step 4 of 11
Built light pole base by pancaking 3 elliptical gradients, then painting slightly to "connect them (the middle "white" layer was just for the highlight on the edge of the base.
step 5 of 11
Used pen tool to draw a pole, then added the beer glass light, free transform to scale it and place it.
step 6 of 11
Applied various gradients and dodge/burn to create shading and highlights on the pole. The added another gradient to create the inner beam, which is somewhat constrained by the glass housing.
step 7 of 11
Added another, wider beam that cast onto the concrete and the base. Added shadow on base, and another shadow on the ground. Then added a layer mask on the concrete where the light would be hitting it.
step 8 of 11
Added "bolts" by creating a small ellipse, and assigning it a gradient, NOT using global light, but changing the light for each bolt in relation to the light from the pole (and one in the shadow)
step 9 of 11
Isolated the couple from David Niblack's image using Quick Selection tool for rough chopping, then pen tool for fine tuning.
Made each shadow by duplicating the "people" layer, filling the people with black, then using the transform to rotate and distort them into shape. Added a 1 to 2 pixel Gaussian blur. Then lowered the opacity of each, according to the intensity of its light source (shown here at full opacity).
step 11 of 11
Added a blue hue/saturation layer and clipped it to the "people" layer. Then created a new layer and added some stars in the sky using a soft brush with some scattering and shape dynamics, and blurred them a bit. That's it.
