**I decided to go with the postwork than to try & upload the texture again as I thought this turned out OK. I will however try to figure this out sometime incase it happens again in the future. The full image took nearly 50 hours to render. I wish now I hadn't gone with so much detail as I've now done alot of postwork to get a slight grunge look to the picture, the original actually looked too smooth. This was also my first work with GR which was part of the reason for the long render time. Hope to have the full work in the gallery soon.**
