conventional deadlift form check

https://www.youtube.com/watch?v=9Xoj4orCaiE
this is 83% of my max i did 5 sets of 3 and this video is the 4th set

any tips on what to improve or what i can fix  i will really appreciate the help thanks

Looks pretty good. Things I saw:

1.  Do not rush it. Take the slack out of the bar before you pull. Steps: position, tension, position, tension, power. Never a need to rush.

2.  Is your upper back rounded on purpose?  I pull sumo and round a bit to get my hips closer to the bar and make breaking the floor easier. My fear for you, and this may not be true as every lifter is different, is that heavier weights will be difficult to get the shoulders behind the bar to lockout. If this is the case keep the lats tight to reach for the bar. If this is not a problem and this set up works that is fine too.

3.  Use your hips to go down and reach the bar. Instead of bending over drive the knees out, ass back, and bend down to the bar. Basically, when you grab the bar you should be in a position to pull. This helps load the right areas and keeps the lats tight on the way down. If the scapulas are protracted when grabbing the bar it becomes impossible to get full tension in the lats.

Hope this makes sense with words

Thanks for the feedback  appreciate it  and about the rounding I usually have someone watch on the side and they say I do  not round maybe it seems like I'm rounded in the video but I will take your advice I'll take the video  side angles next time as well   maybe I can get more tighter always room for improvement :) and I'll try that set up that you spoke about

this is side angle i found a video from the same session  this was the last set  (5 sets of 3)  of 83% of my max   and again i appreciate all the advice that is given thanks in advance everyone

That is a good lift bro. The rounding comes from the scapulas being a bit protracted. At the start having the arms forward of the body may be the issue. Take your time at the top to drive the scaps in towards the spine and down.

Again, many successful lifters like Andy Bolton round their upper back. It is a personal choice. Mess with both and see what works best

thanks for the compliment and yeah i just checked it out in slow motion how can i fix that when i'm at the bottom do i push my shoulders back as tight as i can  or how would you go about it?

Get set at the top and use your hips to get down to the bar.  Usually people reach with their arms and this loses the tension in the lats. I have taught people to do this by having them squeeze a towel in their armpits and keep squeezing while they use their hips to reach the bar and get set to pull

i'll try this out tomorrow and along with other ways and see what works for me thanks for the advice  is there anything else you see wrong besides that little little round?

Nothing else glaring from those videos. Looks like there may be a bit of lockout through the low back (unavoidable as fatigue sets in). Keeping the spine straight on the way down should help there as you can't unbend bent. Might look straight, but it is not. This leads to using the lumbar to extend the hips. Make sure you are taking a big breath and pushing it down as well.

I am overly critisizing here. I am sure fatigue had set in and if you wear a belt when you compete it helps. Keep it up dude

Today I tried different ways and I found I can get tighter in the way I already set up just I wasn't pushing my shoulders back  but when I did this and caused even more tension the bar started rubbing against my shin and when I brought the weight down after a weight it banged into my shins would you say this is fine does this happen to you when you're really  really tight ?

Weight should always be in contact with the body

okay so i definitely felt way tighter than before and today my shin was always in contact with the bar all the way to top i'll try and post a video when i get the chance
