Form check please. and also a 4 or more month progress

Hello fittit here are my stats age:22 sex:male height:5,9 weight 180 give or take a pound or two

started lifting around august but oldest journal entry is in September so ill give my stats from their

Working sets on sl in pounds squat: 115 max:155 Overhead press :100 max:135 dead lift 115 max: not sure at the time bench press: 125 max: not sure barbell row: 105 max again didn't find max then

Now as of November squat:245-working Max: 275+ ohp:125-working max: not sure but hopefully more than before lol deadlift: 250 max:315 bench:175 max: 215 row:140 max: still never found one rep for this.

so pretty much I'm posting this for a form check on my squat and pen delay row, lately i have been getting some elbow pain and i think it's because I'm over extending my elbows out while i lift. also i just want to see what i can improve on because there is always room for it. these videos are at 225lb for squat. "i dropped the weight thinking the elbow pain was from to much weight, didn't really help me" and the pen delay at 140. so any and all advise is welcome, hope to hear some comments
