This is what I did as a result:

We need to alter the shape of this rock a bit. To do this, we will get ride of some upper part of the rock.

Give the rock folder a layer mask and mask the upper part of the rock.

Step 13

So far we have almost finished the composition of the scene. However referring to the moon as the main light source, the front sides of the right and left rock is too bright while the moon is in the upper position behind them. The moonlight does not shine that much on the areas. We will fix this in the following step.

To fix the bright parts, we will give them the other rock texture. Open the rock image and cut out the part used to be texture:

Scale the size of the texture and place it in front of the left rock to cover the bright part of it.

Then give this texture a clipping mask.

Finally, mask some parts of this texture where needed.

Duplicate the texture layer. Move the duplicate downward to cover the rest of the bright parts of the rock. Here is the result I created for our inspiration. Select the left rock and texture layers and hit Ctrl+G to group them in a folder. I named the folder left rock.

Do the same ways to cover the bright parts of the right rock by giving them the same rock textures.

Step 14

Now we will fix the castle. We will get rid of the people seen in the image, we do not need the people. There should be vampires or Dracula living there instead…. LOL.

To get rid of the people we can do this by painting over them, using the clone stamp tool or patch tool. On my own, I used a simple way to do this purpose. Cut out the nearest wall and use the cut out to cover the people. Make sure to give the cutout layer a clipping mask.

Mask the edges of the cut out to blend them well to the main wall.

Do the same ways to cover the other parts of the image.

Step 15

Proceed to add tree behind the castle. Place the tree image in the main document. Scale the size as needed. Position the tree layer under the castle layer. Set this layer to multiply blending at about 50% opacity. Mask the edges of the image where needed.
