All finished but there's a few I'm not happy with.
16A Wine or water (7) E?E??NT - I have ELEMENT of which water is one, but where does "Wine" fit?
17A X & Myops agree (5) ??I?E - I have ALIKE. Clearly Myops is "I" but how does "X" fit. I don't think it means clue 10 as 10A is RECANT.
20D Top award. Mark (4) ?C?R - I have SCAR which is a "Mark", but can't parse "Top award".
