Hey - Thanks for the responses, much appreciated.
Nimblepix - All the dialogue was recorded at the begining of the production process. One potential issue, amongst many, with such a drawn out production process is that the voice of the actor playing the little girl will probably have changed by the time the sound mix is being done. She was eleven when we recorded it so... tricky for getting any pickups to go in seamlessly. Hopefully there won't be any need but it is something I'm aware of.
ok - so thanks again for the feedback, certainly helps to have some objective eyes in there.
Cheers
Matt
