You seem to get a pretty solid position to pull from.
A typical "back" sumo deadlifter from the looks of it.
Only thing that I am ask is whether you have your balance on the back part of your feet at the start of the lift?
It looks like you're a bit on the front of your feet at the start of the lift. At the end of the lift it looks fine though.
But perhaps you can get better power off the ground if you have a little more balance towards the back part of your feet.
Just a suggestion.
Btw, very nice gym.
