First I removed the background of the house using the Polygonal Lasso Tool:

Step 11

You can see that the edges are still very hard after using this tool, especially the bush around the house. To correct it, click Reset Brushes from the brush menu to set the brushes to the default ones. Choose the Spatter 24 pixel brush to refine the edges of the bush and make it more natural. Also, use a soft black brush to soften the edges of the house bottom and blend them with the grassy ground:

Step 12

Use Curves to darken the house a little:

Apply brush masking on this layer mask to refine the light and shade there, to keep the upper part brighter and the lower one darker:

Step 13

Isolate the crow and place him at the top of the roof:

Step 14

Make two new layers on the top. Change the foreground color to black and the brush kind to the birds ones. Paint some birds in the sky as I did below ( remember to lower the size of the birds in the further distance to create a depth look):

Step 15

Make a Gradient Map adjustment layer on the top of the layers with the default colors (black and white):

Step 16

I want to create an eerie mood in this scene. Create a new layer and change the foreground and background to #9d9d9d and #121212. Go to Filter > Render > Clouds:

Convert this layer to a Smart Object. Lower this layer opacity to 50%:

Step 17

Add a mask to this layer and use a soft black brush to remove the mist effect on the sky part:

To refine the mist effect, go to Filter > Blur > Gaussian Blur and set the radius to 90 px:

Step 18

It's time for coloring the scene. Make a Color Balance adjustment layer on the top:

Step 19

Use Curves to darken the scene:

On this layer mask use a black brush to refine the contrast there:

Step 20

In this step, we'll make the red light glowing from one of the house windows. Make a new layer, use the Polygonal Lasso Tool to make a selection on the window below and set the feather radius to 3:

Go to Edit > Fill (Shift+F5) and fill with a red color (#ff0000):

Use the Polygonal Lasso Tool again to make two selections with the feather radius =3 as shown below:
