I agree with N.K. You actually look pretty solid for your experience and age. Much better than me at that age for sure. In my opinion, and limited powerlifting experience, I would actually lighten the weight up. If this is your first bout with lifting, heavy 3's and 4's are not going to help you. Moderate 5-8s, would be more beneficial. Bring the stance in, in the deadlift, along with your grip. I like to grip just outside my knees which is nearly inside the knurling. That'll promote a better leverage on the lift, along with your stance coming in. Youtube guys like George "Babyslayer" Leeman, Vince Urbank, Eric Lilliebridge to kind of get an idea on the stance and grip. Squat looks solid too. Eventually you'll want to bring those elbows in, but that'll work itself out the more you lift, and the more flexible you'll become. Good bar placement for low bar. You don't look off balance, good depth, tight back. In all, nice job. Work on that dead.
