OK, I'll give it a shot. Just remember this is from a short fat old dude that likes to ski low impact.
Start of turn #1 -
you are in good balance.
Then the nerves took over.
Many skiers want to "attack". A aggressive pole plant "ahead". (Pic #2). That is is where things went south.
The pole plant is "ahead" next to the tip of the right ski.
The location of the pole plant blocks the turn. You have to get your boots pass the pole plant location to continue the turn.
So the skis continues to accelerate down the fall line.
A quick push of the tail brings the skis around. Into a skid and body leaning into the hill (pic 5).
Pic 6 - more skid & leaning into the hill to control the undesired acceleration.
Pic 7 - things more or less under control.
Pic 8 - With the excitement from the first turn and adrenaline pumping - a quick stem to start turn #2. At this point, I would have continued with the shaping the first turn to speed control and line development. in a way try to slow things down.
Turn #2 & #3 are basically recoveries from turn #1. Part of the recovery process is mental. Still running on adrenaline. No point picking those apart.
By turn #4 (pic 13) things are starting to settle down. The blocking pole plant is spot on with a open hand around the binding area. That blocking pole plant stabilized the upper body and allows for a pause in the action.
The heart is still pumping a bit fast at this point. a premature start of the turn is initiated prior to cresting the bump. (pic 14). This ended up with a quick pivot which landed you in the trough with a bit of time in the air.
Pic 17 - Heart rate back to normal. You are looking good from there on down.
Your skiing is really nice without the nerves. pic 17 and forward. All the scramble of this start of the run can be eliminated with the calmer approach to the start and a pole plant in the different location. Ease into the run.
Standing across the fall line at the start of the steep run, we are taught at Taos to plant our poles with an open hand directly down the fall line around our rear binding. This rotates the body around to face the fall line and also brings the body across the skis. It also allows the skis to turn NOW. Commitment to the down hill. Keep the ski on the snow.
This is screen shot of the skier at 1:03 from the video posted by
@LiquidFeet above. It shows the pole plant location I am talking about.

Sorry if I am a bit blunt.
