Your neither convential nor sumo. So you dont have the advantage of limiting the rom - like a sumo, or the stability that the convential style provides. So its important to pick one, or maybe include both your routine - but make sure that each set the technique fits the exercise.
Perhaps post another video when you have corrected your stance. Its difficult to tell if your hips rise too fast, as it may well just be that the stance used affected the execution of the rep.
On another note, you head is looking straight forward (as some people reccommend), however, cant speak for you, but me personally it feels too unnatural and forced. I therefore prefer to look 45 degree in front. CT also mentions in his deadlift tutorial to position the head in a natural position.
