You sure, ZIPPED it's 50MB, the original is over 100MB?!? Here it is if you want it Base.psd.zip but I used a bunch of PSDs to make each size. This is the base PSD that I used to create the other sizes from. They do not scle well, that's why I used a different PSD for each size. I could have used a smart group but I ma lazy.
Thanks. It is mainly a lot of lighting and grain against a dark background with some bevels and glow. I used a lot of Imagenomic's Noiseware filters [link] to create the highlights and the dark grain without any halo by-products. That's really the tricky part, to make the gradient lighting without banding.
