SHellback,
Beautiful work on this fine model. Your painting and weathering skill is well-noted and it would be a pleasure to see more of your work!
My only critique would be of your photo quality. Your photos have a really odd sepia-tinge to them. It must be something to do with either the photo background or a bad setting on your white balance on your camera.
I took the liberty of using one of your photos and simply running it through the "auto-correct" in Microsoft Office Picture Manager, and it really cleaned it up nicely. If anything it's a quick fix if you can't figure out the yellowing of the photos. Right is your original photo. I think the left, corrected photo really is more flattering to your finish?
