I find it somewhat uncool when a double definition clue uses the very same meaning of the answer word in two faintly different ways.
Example: 25 Across: "Signs of life in blinks of an eye".
(I call that a 1.1-definition clue.)
Similarly, it's not cool when a clue uses a word with the same etymology that appears in the answer. Case in point: 15A.
As long as I'm complaining, I'll mention that 19 Down seems poorly written: It's just too difficult to find a valid justification for it.
On the third hand, the symmetrical fruits were a nice touch.
