Welcome. You are a strong young lad. What are your height, weight, and age?
Impressive lifts. How long have you been at it?
Comments on lifts: Squat: You need to go about 1 to 1 1/2 deeper.
Bench: Arch your back and keep chest up. If you do this your head will not lift off of the mat.
Dead: Once you grab the bar do not release it.
I make mistakes after 8 years of lifting. I'm certainly not perfect but those changes will make your lifts more valuable.
