I really like to change the composition.
So just transform this layer and Flip it.







You are actually having all layers to play with but only horizontally. See?



Now flip the layer creating some kind of recognizable tree silhouette.







Now you'll se how is very convenient to have this on the separate layer. Create a copy of this layer. Bring the fill to 70%-79%.



See these cool waves in the center; I've dragged the layer horizontally.
Now create anew layer mask that reveals all (the effects on white).
