And here I thought only JJ Abrams was a slave to lens flares! Terrific build. I have not even cracked the cellophane to open the one I have in the box yet, it's been sitting there for 2 years gathering dust as I slave away on the Zvezda.
I would however suggest toning down the use of multiple flares on a single image as it takes your showcase from realistic to the realm of CGI, unless that is your intent. You would likely only ever have ONE lens flare from one single point source in a natural capture. The laser blasts might be an exception but I would suggest fading one to 50% or more after applying the flare, especially since the X-wings do not fire simultaneously but with a staggered fire rate from each tip.
Your engine glows are okay in colorization, but where we are seeing the build from the front - you would not have perfect circle glows overlapping the edge of the engines, you would have the hard uncolored edge of the engine in foreground. Something like this:

Anyway, the build is awesome, just offering a my .02 on the Photoshop.
