THX1138 - Yeah it has similarities with the bridge piece - must be my liking for scenes with big swooping bridges/roads

Jay - It will be a static shot but it never occurred to me that this would be good for a matte painting. Cheers for pointing that out Have you got any examples you've done that we can look at?
Might it be helpful to throw a basic grid texture on the buildings so you know the perspective angles or is that a bit of overkill if it's going to be a background layer in photoshop?
One other thing is - how do you render out just the reflections or shadows? I've heard it mentioned in lots of threads but have never seen ot tried it yet.

Jsprogg - neither would I, its great that professionals like jay are around to offer good advice

Steve - no probs, I might mix and match it a bit to start with till I get into the flow of matte painting (never really done it before but it looks great fun)

happymat27 - thanks It is definitely more of a 'utopian' shot. I've got some manga theme and influence running through the idea at present so it'll probably stay fairly clean.
