Basic Blending
1. First open both of your images, then make a new blank canvas ( file>new) the size are 814x1000px. Then i draged Piz onto the canvas and resized it so it wouldnt be too big ( edit>free transform ). Hold the shift button down so when you resize the size still stays equal. Then drag Veronica onto the canvas, i did that same as i did to Piz, resized it so it fits. Now Veronica should be overlaping Piz :
2.Now take your Polygonal Lasso Tool ( L on your keyboard). I then select around Veronica on the left, not to close to her clothes. Then once i finished that i push delete :
3. I then took the eraser tool (E on your keyboard),I then zoomed in and then started earasing around Veronica.
4. Then i flattend the image ( Layer>Flatten ). To make it looks "more togther" i went to Filter>Noise>Median, i put the radious at 1px. I then went to Filter>Artistic>Smudge Stick. The went to Edit>Fade Smudge Stick, i put the opacity at 70, and set the layer to Soft Light.
My final product looks like this :
