honestly, would rather "be like the guy on the right"
wide shoulders get you noticed in normal clothes, that little dude dressed is not gonna look big, ever.
But we don't know their exact height/size either.
The fella on the left may have the worst clavicles of peace and the most unfortunate biggest head, but he may have been cropped down in size to fit the picture as well.
He could very well be taller/bigger than the right fella.
But fella on the right has better proportions of course, just need to add muscle and then he's set.
