Any Graphic Artists out there ??

[clee]

Been a bit slack workwise so I've been messing about with a 3D model of the GTA .I started this ages ago ,it's not to bad but I've not got a good Rendering package and not a clue how to do all the arty stuff ,adding light sources ,materials ,reflection etc,etc .
Anyone willing to have a pop at colouring it in for me ?
Just want to see if it's about right .I can export a few different file types so it should go in to a renderer .
