Look at the first image (beforeafter.jpg), photo on the right (Dec 2016). The corner of the door is over his right shoulder. If you go straight down, it should come out behind him somewhere around the break between his first and second fingers. But it doesn't. The door sticks out below his 3rd finger. If you look below that, the break in the carpet doesn't line up either.

He probably photoshopped his abdomen to make himself appear skinnier, which is a shame. He's made incredible progress, and dishonesty only detracts from the hard work he's obviously put in.
