You may need to go back and forth between Photoshop and Bryce making adjustments to the pic until the piece is how you want it. Once the shape is right, you can concentrate on the material...use Bryce materials or perhaps a custom Photoshop created texture applied in the Material Editor. This is a quick render with a basic preset...just to show the end result of a sloppy job.... *grin*
