After retouching. I preferred Kate's facial expression in image 1, and Drew's facial expression in image 2 so I decided to combine the two. I roughly cut around Kate's head from image 1 using the lasso tool and then pasted it onto image 2. Then, I used a layer mask to blend the two layers. I used frequency separation on Kate's arm to smooth the skin and used the clone stamp to remove the leaf from the top left corner as I felt it was distracting. Finally, I clicked save to link the edited version back into Lightroom where I applied my usual editing style (split toning, contract, sharpening etc)
