Thanks for the comments & critiques people, it's very much appreciated.
Ken, the whole model was textured in sketchup - because 3ds max reads the UV coordinates once I bring it in and start setting materials up. Though in hindsight there are things that I should have textured in max such as those wooden boards on the underside of the roof canopy...
I spent absolutely ages moving the texture on each board (they're all individually modelled) around to prevent tiling and also to give me the chance to apply different amounts of hue/saturation/reflectivity to each one in max. However I've since learned a far quicker way of doing this winthin max. I did the same thing with the "sleeper" fence around the car park too.
The only non sketchup elements are the foliage, cars & people.
