Found this a bit of a brute. Although, once the answers were in, it was clear that most of the clues were tough but fair - e.g. 13D and 19A. But COD 14A by a country mile.
The exception was 27A. 'Creature that eats'! Seriously? As opposed to a creature that doesn't eat?
Yevrah - try removing the brackets from the clue, which at least might clarify the definition.
