About that second batch:
"There was scope for more musical ______ to add further interest."
"Your tempo was well maintained. Some ____ ______ ?
The first mystery word is (again!) "unease." The next word, I think, might be a word that he/she made up.
Something like "latterly."
(BTW, that really is a word, but I don't think I've ever seen it before.)
P.S. Now it's our turn to write comments for the examiner!
I'll start: "Your penmanship is terrible and extremely inconsiderate. You need to do something about that immediately, or else people will keep pulling their hair out and cursing you over your handwriting for the rest of your life, which they've been doing whether you know it or not."
