If he was 5'6 I wouldn't bring this shit up but since he's only 5'5 and a 1/2.... well.
Your head is disproportionately small for your upper body it's ridiculous. Your arm is literally twice the width of your head, that's unheard of. Stop bicep curling.
Im going to go a head and guess judging by your oversized pants that your legs are skinny as shit too, further making your physique fucking baffling. You have a tiny head, a massive upper body and most likely slim chicken legs.. Picture that. I will however commend you on the extremely oversized pants though because it ALMOST creates the optical illusion of you not being a midget.
