you look great bro, detail is coming in nicely.. and those arms and that back are huge!
Posing is really good for so far.
But, bring your front elbow back further on the sidechest, and have the back arm push against your pecs.
on the quarter turn to the side, bring your front arm in a bit closer, where theres is just a small small opening between the front arm and your back. I mean you need to close that space a bit more. Also, on your bent back arm, the judges are gonna make you straighten that out, keep slightly bent, and slightly towards the front pushing against your chest.
Thick bro! Looking great... can't wait to see the transformation.
