Step 8

Place the nebula 1 image over the picture, then change the mode to Hard Light 100%:

Add layer mask to this one. Use a soft brush to reduce the nebula effect in the sky and on the lake:

Step 9

Duplicate this layer, flip it vertically and move it down to create reflection for this nebula effect:

Apply Motion Blur to this layer:

Step 10

Make the nebula 1 layer and its reflection selected then press Cmd/Ctrl+G to create a group for them. Change the mode of this group from Pass Through (default group mode) to Hard Light 100%. Make a Curves adjustment layer on the top of the layers within this group to change the color of the nebula effect:

Step 11

I used a Color Balance adjustment layer to make this effect more vibrant:

Step 12

Make a new layer on the top (above the nebula 1 group). Change the brush to the cloud ones. I used number 1252, color #fcf5db to paint a cloud at the middle section of the lake:

Step 13

Duplicate this layer, move the lower down to make reflection for this cloud after flipping it vertically. Lower the opacity of this reflection layer to 50%:

Use layer mask to reduce the top of this reflection then apply Motion Blur :

Step 14

I painted another cloud (number 1369) at the right of the first one:

Make reflection for this cloud as done with the first:

Step 15

Paint two other clouds at the left of the first and make reflections for them:
