This is scaled wrong. Dorian is taller/larger than Phil.
correct, this photo is to point out the size and muscularity of all muscles that are in view for comparison. in all fairness however, dorian's photo is obviously not around contest time, but phil's high points are impressive, especially the delts, traps, thighs, upper forearm (dorians are lacking in comparison)
points to make: dorian's naturally wide pec's and density are impressive. phil makes up for not having wide pec's (structural) by piling on the thickness around the front delt region and across the upper chest/clavicle region. both of phil's arms are very consistent in size and muscularity; in this pic dorian's left arm is not equal to his right in size and proportion.
