In that picture, Ramy is clearly destroying phil.
I dont see Phils arms as more detailed than Ramys in that picture. Its comparable. Ramy has an X frame, better lats, chest looks better. In that picture, he looks way more complete (from the front) than Ramy.
Look at the detailed, separated split between bis and tris that Phil has, and compared that to Ramy. Also look at the splits in his bicep on that one side. Ramy's arms are bigger, yet he doesn't have that separation

Phil has a narrow structure, lats, shoulders, etc. what separates him from another narrow guy, Flex Wheeler, is that Flex had a smaller waist and a more dramatic taper when doing the Front Double biceps. This is a pose where Phil is very beatable in.
