Hey man, lifts look great all over.
For your squat it looks great, i personally squat with different form and heels, but you get depth and you look strong. The only thing I'd recommend is not to neglect front squats to keep your quads strong so you get out of the hole with max weights.
Your dead lift was a good strain, congrats. The one thing I noticed right away is that you let your hips shoot right up from the start and sumo stiff leffed it... that's an actual technique.
One of the things with the way you squat is that you don't get very good quad stimulation from it, and when your quads are weak you'll have a tough time getting deadlifts started off the ground as at the start is all leg extension if you're doing it properly.
Deadlifts to the knees do a tremendous job of building the start of the dead lift. They teach you to lock your torso and drive with the legs.
Your bench looked good.
I know you asked for advice, but between you and me I'd probably delete the thread and just stick with your training partners if they're good... note I said good and not experienced. I can take a dump and put it in a box and let it sit for 5 years... but it's still an experienced piece of crap.
