You know I keep forgetting about that nice and critical part of posting
As I have comments on I seem to be blind about that bit, but I don't go out of my way to say something bad, only one when it was blatantly obvious they were using shaders and not lights and not telling people lol

Put my nose out of joint as when you render for a vendor with shaders it hides all the bad skin mats, makes me so angry so I usually tell people what lights and shaders I use, for me thats the only thing that rubs these days.

As for the rest, I can remember my first render, and all I can Say Is OMG, lights are your freinds, find the right ones and your artwork shines :)
