lilTanker saidI'm personally more concerned with his neck changing length in two photos... *coughs*
DING! I noticed that too, sorry Ari. That dude is peaced together poorly. You do know i am a graphic designer right? Colour hotspots, even artifacts have nothing to do with it
actually man.. you are missing a lot, the body isn't pieced together the torso is one torso, there are a few offs though with the harness on the left and with the neck changing lengths, lighting and markings, but the images are too small.
Poorly resized images done using php can create all sorts of artifacts and not properly blend pixels and realjock has a horrible implementation, there are artifacts through everyones photos if you look at them properly.
Even the neck problem can be accounted for slight changes in camera angle and or height, lighting, head position and the like giving the illusion of length or shortness.
I wont express what I think think, but just wanted for you to be aware that there might be more happening due to external influences rather then photoshop only.
