I'm not sure it was because you idolised Zyzz, that you were not well recieved. I think you know why.
Anywa,y all that aside, you're upper body looks good. But you should post all your mandatory poses.
Upper triceps are thick, chest is anatomically well-structured, you lucky bastard
But yes, I would lift the chest a little and pinch the 'blades together a little.
Actually what you should realise about competition posing is that there is no 'right' or 'wrong', just what looks BEST for YOU. So experiment and have friends take pics from floor level (or you stand on a table) since this will replicate what the judges see and allow you to pose for maximum visual effect.
