What I really like about this picture is the look on the face of the guy in the back ground. He’s staring at that bicep with such desire!
It’s not clear until you look at the picture closely, but the guy in the back appears to be flexing his arm as well. Only it is completely eclipsed by the biceps of the guy in the green shirt.
The guy in the back just looks like he’s both disappointed in the size of his arm, and simultaneously longing for the bigger muscle dwarfing his arm. It’s disappointment, longing and awe. No comparison. Just domination.
