Step 9

Select all the knight and debris layers and press Cmd/Ctrl+G to make a group for them. Change this layer mode from Pass Through (default group mode) to Normal 100%. On the top of the layers within this group, make a Curves adjustment layer to darken the knight and the disintegration effect:

On this layer mask, use a soft black brush to refine the light and shade on the knight to fit the background. You can see the results on the layer mask and on the picture:

Step 10

Use a Hue/Saturation adjustment layer to reduce the redness of the skull and other details:

Step 11

To reduce the lightness on the top of the skull, make a new layer and use a soft brush with the color #958673 to paint there. Change this layer mode to Multiply 100%:

Step 12

Place the fire image in the foreground and change the mode to Screen 100%. Use a layer mask to remove any white edges remained.

Step 13

To add a glowing effect to the fire, make a new layer under the fire one. Use a soft brush with the color #281b01 to paint on the bottom right of the image and change the mode to Linear Dodge 100%.

Step 14

Make a new layer, use a soft brush with the color #e6802d to paint on the bottom right again. Change this layer mode to Hard Light 100%.

Step 15

To make the fire reflection on the knight, create a new layer under the fire and glowing light ones. Use a brush with the color #ffd10e to paint on the strokes of the knight clothes and sword. Change this layer mode to Overlay 100%:

Step 16

Duplicate this layer to make the effect stronger:

Step 17

Create a new layer and use a soft brush with the color #ff850e to paint more red effect. Set this layer mode to Overlay 100%.

Step 18

To change the light and contrast of the image, make a new layer on the top. Active the Gradient Tool (G) and choose Radial Gradient with default colors (black and white). Drag a line from the top left to the bottom right of the canvas and change this layer mode to Soft Light 100%. Add a mask to this layer and use a soft black brush to erase the right of the fire area as I don't want it to be affected by this Gradient layer.
