pretty cool but...
first, like others I'm sure have said (can't read reviews yet) it's a bit slow paced for a war piece. The sound effects were a bit... canned... well, only the bomb effects really.
second. One thing that drives me nuts in flashes is when half of the design is like art and the other half is thrown together crap. I see in most flashes, and in this one, excellently drawn guns and vehicles, then shoddily thrown together buildings and people. The people in your flash were good, but the buildings deserve just as much attention as the planes, despite the low screen time. Look at how smooth the soldiers at the radar station were, and they got only a few seconds. This is why I gave you 8 for graphics (the planes and people) but a 2 for style (you had no solid style, but a mix of styles).
Good job and I hope you make the conclusion since I'm too lazy to google it and find out what happened ;)
