Make a new layer and use the same brush but lower the opacity of the brush to 25-30% to paint a soft shadow of the model on the ground to fit the light’s direction.
Create a new layer above the model one and use a soft brush with the color #dfc0a7,, the opacity about 18% to brighten the part below the cheek a bit.
Make a new layer and change the mode to Multiply 100%. Use the same brush to paint on the part below the cheek to darken it.
Add a new layer and use a soft brush with the color #d6d0cb to paint a small part below the left foot. Change this layer mode to Multiply 100%.
Select the model layer and the shadow ones as well as the ones made in the step 13 and 14 and hit Ctrl+G to make a group for them. Change the group’s mode to Normal 100% and add a Hue/Saturation adjustment layer within the group. Bring the Saturation values down to -24 and on this layer mask, use a soft black brush to erase the legs to keep some warm tone there.
Create a Curves adjustment layer and decrease the lightness. On this layer mask, paint on the contour of the model to reveal the light there.
Make another Curves adjustment layer and increase the light for the contour and some parts of the model. The selected areas show where to paint on the layer mask.
Add a Color Balance adjustment layer and alter the Midtones and Highlights settings:
Open the house image and use the Move Tool to drag the house into our main canvas. Place it onto the model body.
The top of the highest tower is hidden. To fix it, add a mask to this layer and use a hard black brush to remove this part and the middle to reveal the model face, arms and dress.
Come back to the original house image and use the Polygonal Lasso Tool to select the top tower and place it onto the top of the house. Use Ctrl+T to resize it to be smaller than the original one. Set this layer below the first one.
Make a group for the house layers and add a Color Balance adjustment layer to change the color of the house.
Create another Color Balance adjustment layer to add some light warm tone to the roof of the towers on the left (from the viewer). On this layer mask, paint on the rest to remove the warm effect on these areas.
Use a Hue/Saturation adjustment layer to desaturate the color of the light on the windows.
Make a Curves adjustment layer to darken the house. On this layer mask, paint on the contour of the house and any details you feel too dark.
Make another Curves adjustment layer to bring more light to the house’s contour. Paint on the rest to keep its shadow and contrast.
On each of the house layers, make a new layer, change the mode to Overlay 100% and fill with 50% gray.
Activate the Dodge and Burn Tool (O) and use the Burn Tool with Midtones Range, Exposure about 15%, the Dodge Tool with Highlights Range, Exposure about 40-50% to paint more light and details for the house. You can see how I did it with Normal mode and the result with Overlay mode.
