Physique competitor checking in!
I agree with your original post, you're far too lean for physique. Other than leanness, I would adjust your posing a bit. I realize that you could have been in a transition when your stage shot was taken, but try to keep your chest raised and don't flare your lats as much as you were.
Also, it looks like you're flexing (which could just be due to how lean you are), remember, we bikini guys need to look ripped without trying to look ripped. Flex, but don't give the impression you're flexing.
Show your teeth dude.
