Hi Jay,
hehe, I thought that it WAS mainly bang a render out and then touch it up in photoshop, not to actually take loads of layers and then play to get a nice effect afterwards (which is much better now that I know and have tried )
Yeah I really liked the effect of the reflections in the rear central skyscraper and stupidly thought it would look good everywhere (like you say, not all buildings need to be shiny). I've knocked the blinn settings down so hopefully that and maybe not using the color dodge will bring things back down to earth a bit.
here's another play but its mainly getting the specular levels down a bit and slightly moving things around to better draw the view in. Once those bits are finalised then I'll render the relevant layers out and start working things up
Si
