Superb. Looks like you caught the gully in really good nick - perfect neve! Well done.
When I did this back in 1999 the snow was very unconsolidated, giving little purchase for the axe (a single walking one). The cornice at the top was an overhanging nightmare of soft powder that took me ages to dig through.
It was unquestionably a dangerous situation and I should have reserved this fine climb for the right conditions - as you had.
Great photos and the drone shots in your video are very impressive.
