If SOW is on track, then all of these suggestions are sort of pointless since the game should be pretty much ready to be released (sept-oct release). If the game is not on track then there might be time to do some of these additions, but I'd be more worried since Oleg mentioned in an interview that November was a time when it might have to be released due to financial reasons.

Also, I wonder how many of those explosions you posted are actually 3d. Your helicopter never gets any closer and you only see them from pretty much one perspective. Maybe they are 3d, but maybe there are only something like 4 predetermined explosions and if you were to overfly one it would look strange.
