Really not a lot of work into this post processing wise.  Nik Software’s SilverEfex Pro did most the work.  After doing my initial Level and Curve adjustments in Photoshop, I also applied two unsharp masks of 150, 1.5, 3 and 20, 50, 0.  I then ran the finished image thru SiverEfex Pro and applied the Sepia preset.  I then took both the color version and the sepia version into Photoshop CS4 and blended the layers.  Click on the image to see a larger version.

ENJOY!
