Wow, looks really good!
Im especially fond of the cannon smoke. It looks really good even though its not 3d. Impressive! And the changes at altitude, wonderful.
Now for a question about explosions.
In reality, even the large bombs have very little fireball (I can only speak from my experience watching JDAM's and other ordinance, mostly smaller than 1000lbs. Larger than that and I don't really know!). Its mostly just dirt and dust thrown about, which is covered VERY nicely here!
Would it be possible/feasible to remove or GREATLY shorten the length of the fireball in explosions where no target is hit, but to have it as it is now when a target is destroyed, somewhat reflecting secondary explosions.
EDIT: Also, the Flak bursts from the low particle effect pack just look too cool! Perhaps they can find their way here?
Regardless, this is a wonderful compilation here. Many thanks!
