The "impact flashes" sound like quite an undertaking, but I'm sure along with all your other alterations they'll give everything a more realistic look. And since you've decided to address such a minute detail, I was wondering if you'd considered putting in comm mics on/off sound effects for clone dialogue. This was brought up before and I think it's an excellent point. Stormtroopers need those microphones inside their helmets to be heard, but apparently clones can talk REALLY REALLY LOUD.
I know music alteration is a big thing in SotDS, which IMO is one of its best aspects. Anyway, I was listening to "Rite of Spring" yesterday and it struck me how Star Wars-like certain pieces of it was. I had no specific thoughts on any scenes to use it, or even what parts to use, but was curious if you had taken from Stravinsky's work.
