As another non-professional instructor, two errors: stiff legs fixed in the semiflexed position and backseat driving.
On the plus side: parallel skiing, excellent fluidity of motion and good use of poles, especially timing. The guy is not intimidated by the slope, but obviously upset that he is out of tools to attack it. Level 6/7 ?
Suggestion - take advantage of the good and give him shorter poles to force his body into a lower stance and softer boots to make it possible, and he will do this slope as if it had been a green groomer.
I was making same errors several years ago. Then I switched to 44" poles from 48", and by the end of that season I was cruising on crud and smoking moguls. Now my poles are 46", but the basic correction has been made.
