My (honest opinion) on your trailers.
There is a real mix of quality in your shots from the trailers. Some of the shots are absolutely beautiful and extremely professional looking and wouldn't look out of place in a Michael Mann digitally shot film (i.e. 'Collateral' or 'Miami Vice'). Others, look far less polished but these are down to lighting and shot choices more than anything and could be fixed somewhat further in post (I am assuming this isn't a finished product).
Really, really love the location shots, the tunnel shot and ALL of the shots in low lighting - impressive.
My other criticism (and it's very minor) is the font used in your first few trailers (the blue one). It looks very amateur-ish - I'd stick to the font you've used in the final trailer from now on, but that's just my personal opinion.
Lastly, the sound isn't completely crisp - maybe this was more noticeable as the quality of your images is very good and I noticed the sound more. There is a lot of background noise/feedback in your recordings - what mic did you use?
Positives
-----------
Some EXCELLENT low light shots
EXCELLENT location/establishing shots
Negatives
------------
Some shots are far less impressive than others (esp your brighter shots)
Sound doesn't sound very polished or crisp (lots of feedback/background noise during dialogue)
Regardless, I genuinely would watch this - what are your plans regarding distribution?
