I've been having people on various forums ask me how I did the third picture. Here is the original:
I used Photoshop. My primary tool in this case was the clone stamp tool. On Mac, simply select it, then option+click on any surface you wish to copy. In my case, it was the lower door. Then, you can paint with the texture you selected and I used that to replace the hand. I did the same with the boxes behind my husband's arm.
After that, I got out the smudge tool and set the strength down to 5%. Then I ran the smudge tool down around Rhoskel's butt, thus making sure it didn't look pixelated where I was removing my husband's hand.
Add in effects and done! He's knocked backwards.
