I don't know what it is, maybe the angle or something, but your leg shot looks awesome. Looks a lot better than the squat number you've posted here. If all I saw was the leg shot, I would have assumed you already squat 400+. TEACH ME HOW TO POSE!
Anyway, congrats on the progress to this point, both in getting stronger and losing the fat after. And I totally agree that you should keep the fat off forever. I've managed to stay lean my whole life, and believe me, you can continue to build muscle while staying lean for a long long time.
Also, good work on balancing life. 3 kids and a hard job and never skipping a meal? That's awesome. I miss a lot of workouts and meals, and I've only got 1 kid, lol. I average 2 meals a day.
As to your last comment, you definitely can see the results you want, given the dedication you've expressed here, it just takes time. But getting over 20% bodyfat will never be the way to go. I've squatted 560, deadlifted 620, and benched just under 400 while being around 9% bodyfat. I've also been lifting on and off for 15 years. Trust the process and keep working hard. If you want some advice on programming, feel free to ask away. From your appearance, it looks like you've largely got diet in hand, to be honest. You've found ways to add a lot of weight, and you've been able to cut. So you clearly understand how to manage macros at least to some extent.
