You have already heard this a lot, but this build is absolutely stunning! I love every detail and all of the hard work you put into this. Looking at the photos of the back of the window really shows the amount of technicality and clever parts usage. I hate saying this but the only thing holding this back, (if at all...) Is the lighting. The size of this I'm sure makes that task more difficult. I know the scene itself is rather dark so that was done wonderfully. Maybe its the color of the light... I dunno.... I'm rambling on... The fact of the matter is this is one of those scenes that needs this quality of building and you did just that! Excellent job!
Going back and looking at the photos, are you using the flash on your camera? That would explain the odd reflections, bright spots, and shadows. You should try using a background light source and turn off the flash feature. Play with a lamp a bit or even open up a window. (That's what I usually do.) The hard part being keeping that dark feel. That will boost the quality of this MOC to even more Epic proportions.
