You could train for physique a while compete and then transition into bodybuilding if you don’t enjoy physique. Kind of works well because you’ll get bigger and more aesthetic training for physique which you’ll need anyway and then, if you choose to, get even bigger while keeping your aesthetics for bodybuilding.
Deadlifts and torso thickness: I’ll be straight with you and say I deadlift, squat and do loads of beltless work because I think it’s beneficial for me and only thickens the waist minimally. That said, for you whether by genetics or training you seem to have a waist on the blockier side already.
This has to be offset by posing and growth in your lats and back (and fat loss but you seem lean already) to achieve that V Taper. Trap growth will likewise detract from the physique look so I can’t see deadlifts being beneficial to you. Probably best to priortise and hammer (read progressive overload) vertical pulling variations and horizontal low pull variations for dem lats.
Delts/Shoulders can’t be too big IMO even with all the genetics and drug usage in the world so keep doing whatever you’re doing if it’s still growing. Your delts look great from the front but from the side maybe a bit more rear delt work would be beneficial.
Chest is k. Biceps… maybe a bit overpowered by surrounding muscles e.g. front delt and triceps. Calves… idgaf
Physique posing came very naturally to me when I first tried it though some of my friends can’t get it down and end up having 0 taper. There’s only a couple of turns and you don’t really pose to show muscularity anyways. Watch a couple of vids online. Find a mirror… actually use any reflective surface from the gym locker room to car windows and puddles and hit a practice pose at every opportunity (Will look like a douche and cringey af but at least it’s more subtle than a front double bi)
