Correct Deadlift Starting Position?

Hello there.
I’m a teen with a height of 5feet11/180cm with relatively long legs compared to my torso. This fact affects my deadlift starting position so I need YOUR help on determining which one is right.

I’ve been having back soreness/pains lately and if that is a result of a bad starting position, YOU be the judge!
Legs are shoulder width apart, I start the pull with pushing through the heels while squeezing my glutes and abs as tightly as possible. I also squeeze my chest up during and starting position.

Give me a minute to post photos.

Your lower back is VERY rounded in this picture. Do you have flexibility issues? If yes, work on them. The starting position in the picture will wreck you in the long run.
