Process of making my models lips leopard print

This is the picture that I will be using. 

First of all I duplicated this layer. 

Then I added the leopard print image on a separate layer. 

I then moved the layer with the leopard print so it was in between the two layers with my model on. I then erased the lips from the top layer. 

By activating all the layers the leopard print patterned apart as looking like the lips. 

I lowered the opacity of the leopard print to 40%, making it look more real.
