I started by selecting the hands and deleting the background and other hands with the quick selection tool. Then I opened the coffee cup image and selected only the coffee cup. I added a background image of a table to set the coffee cup. Then I tried to make it seem as if the hand was emerging from the coffee by using the blend and clone tool. Lastly, I added a phone to the open hand. I finished this by adding a grain filter to all the layers to make the blend and images a bit more seamless.
