Dayum MM! HAWT! Mega props on presentation & you look like you had a blast! That smile is definitely what gets the crowd into it! I couldn't give any comments except just need a little more thickness. Now that you've seen what nature gave you to work with -- if you choose to continue w/ competition, the next round would be to experiment w/ a serious bulker (natural I mean) and just keep working on pushing your body's 'foundation weight' up. That's an 'over time' thing, if that's your goal.
Looks fantastic! Seriously -- nice symmetry, you cut up really nice - striations, obliques, xmas tree just standing there. Congrats!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
