Very nice, lovely to see the night and day scheme on the spitfires: I was thinking you had missed this out.
Out of interest, will it be possible for the 'pop' feature of objects to be sorted out? if we look at shot 4, one can clearly see trees which look quite crisp against terrain which is blurred. The transition doesn't look seamless, but I'm sure this can be fixed. (I bet you knew that already, didn't you?!
)
Also, in one of those shots, are the spits flaps partially down? I though they only had two positions....?
