Hey man, I like your lifts, good work.
First of all... you're wearing knee wraps, so that's one reason why you're squat is above your deadlift, when I used to use them I'd get 50-70lbs out of them.
Second, your squat form is awesome, your knees go very far forward and you stay nice and upright, it was a pleasure to watch.
3rd, you seem to have a fairly long torso, and not the longest arms, that makes deadlifting a total nightmare, I'm in the same boat. Fortunately, somehow your legs are also long. How tall are you and what inseam are your pants?
4th, your deadlift form is off, Black angus gave every good advice there. Something I'd highly recommend is 5 sets of 3 at 80% of your max, and pull it to your knees, yes your knees. This will really teach you to drive with your legs. Follow this up with pulls from the knees, preferably off boxes for 5 sets of 3 with 90% of your deadlift max. add 10lbs to each lift for a month. This would go a long long way to build your form. I don't recomend bringing in your grip, as it seems like your legs are in the way, but do the best you can.
Good lifting dude, and good on you for reaching out for help. And don't mind black angus, his heart is in the right place, he's just an angry man, lol.
Let me know if you have any questions
