Creating Dimension

First I adjusted the levels on the background layer. Then I found a rock shape I liked, selected it, contracted it by 2 pixels, copy/pasted into the rock image that I liked (the one above), saved the selection and discarded the original rock layer. I then copy/pasted that rock using the selection from the other rock and copy/pasted that on top of my background layer. Or you can just select a shape you like using the selection tool.

I then adjusted the levels on the new Rock Layer. The colors on the bottom tip were too yellow and looked odd so I selected the area, copy/pasted it to a new layer and adjusted its levels. I then Merged Down (Ctrl + E or use Layers Menu) all the way to the Rock Layer. I locked the Rock Layer.

 I loaded the Rock's selection and pressed Ctrl + H to hide the marching ants. Then I began to shade the rock. I chose ground, plant (near bottom) and sky colors (near top). I set the Modes to Multiply and adjusted Opacity (on your Layers Menu). I then made a small shadow for the rock on the ground using a selection with a 3 pixel feather.  I merged all the Shading into one layer once I was satisfied. You can then click the layer on and off to see the difference.

This is a fairly simply manipulation. Take your milk splash into Select - Color Range and Eyedropper + all the black area then click ok. Then Inverse the selection and copy/paste it onto your main image. Edit - Transform - Scale to the size you want. Erase what you don't want. Then add color. Use Photo Filter (under Image - Adjustments) and go with the Warm Filer. Then go to Layers - Layer Styles - Inner Shadow and make the adjustments. Then click on Gradient Overlay and make those adjustments. You'll want to experiment with them. But Overlay for Inner Shadow and Linear Burn for Gradient Overlay work pretty good. I also added a small Outer Glow to some of the spots under her hand.
