My picks

"everything" , keep the first e short
"control", "tr" sound strange
"number" sounds like "namber"
"unimportant" "an eye" "an unforeseen" "on a big scale", should all combine the "n" with the vowel following it. e.g. "an eye" should sound like "a neye"
"prelude", the accent should be at the beginning, on "p"
"Sydney", d was over-emphasized.
"immediately" sound like "immedia l tely"
"hundreds" sound like "handreds"
"behind" sound like "behand"
