Wow - that is pretty damn lean. I never could have imagined he could get his body fat that low. He clearly put a huge amount of focus on diet and cardio.
Its a move in the right direction. I think he has also brought his thighs down a little in size to give himself a better overall balance.
I think the aim should be to come in that lean, but yet with a fuller look. I suspect he would have looked at his best a few days after, once back eating more carbs, he would have had a fuller look, yet been as lean, but more pumped.
He should now focus on staying lean, building qualiry muscle, with a moderate carb, high protien, low fat diet, with regular cardio.
Overall, nice work Trey. Look fwd to more progress and your next contest.
