Matte Painting: Rough Version 1

So I've been working on a matte painting for my opening shot. It is a panoramic view of the city below, with our hero crouched on some sort of high up platform or rooftop like in the computer game. This is pretty much how I want the layout, though the comping is still quite rough. Noise and grain are issues due to the quality of some of the images I am working with.

I have also put together a sketch for a market place type setting which I hope to use for the fight sequence on the ground. However more on that later.

Currently I am researching 3D projection and camera moves in After Effects. I feel I have a pretty good grounding on this already due to a very comprehensive lecture series we had last year. However it never hurts to go back over these things, and after watching a few tutorials I feel I've picked up a few handy tips which will help me on my way with this. My one dilemma is tracking the camera move. I am keen to do a camera move in the studio, and track this to a digital camera in After Effects, however I have yet to work out how to pull this off.
