It looks like you had it on 2x playback speed, especially when it shows the arrival over the enemy airfield and the enemy planes.
I get what you're trying to do and I like it, but there's a lot of view-jerking (trying to hold the view so you get the footage), and that detracts a little.
One flaw is that there were fade ins/outs that were different sizes, and you could see the black edges change with the cross-fade. That can be avoided by using a smaller project resolution (basically "chopping" or "cropping" the edges off, so you can't see that).
I almost felt sorry for that mossie that lost gas and #1 eng. The music really helped.
P.S. What's with your gunsight? Your head is way above normal. Is that just for the movie, or do you really fly like that??
