Here are two new renders. There's a bit of an issue with them. An unwanted shadow caused by a rogue light, and a detail texture was turned off. I didn't notice until after these two were rendered so I'm posting them for now and I'll redo and update them tomorrow.
Blend files will be uploaded during this coming week and I'll also be sorting out the plan for Christmas break. I'm off work from Dec 12th (I hope) but render wise I will probably be taking Christmas week off. Will confirm later.
Edit: The new versions of the original images and the rest of the set have been uploaded. Hope you enjoy.
