Hi Ron,
It's difficult to improve upon perfection, but I thought that a little cropping might make the image a bit more powerful. I also nudged up the brightness.
I hope that you like it!

This is another one of the many shell casings that I found this particular morning. You can see the mud still covering the skin on the back end of this shell.
I used Hue and Saturation adjustment layers and masks to remove some of the blue color cast. I also toned down the highlights and the greens a little bit.
