Hi James,
I generally like to shoot things faithfully, only abstracted by selecting a close detail. However, I think this image could benefit from leveling the light to reduce the 3-dimensional aspect, and boost the shadow contrast a bit.
One way of doing that could be by making an average vertical luminance profile, and apply it as an inverted Overlay blending layer or something. In Photoshop, make a duplicate copy of the image. Resize the duplicate to 1 pixel width, but first uncheck the "Constrain Proportions" box for aspect ratio. Now resize it again to the original width, and invert the result and desaturate it. Shift drag it with the move tool to your original, it becomes a new layer. Change the blending mode to "Overlay". Now you can play with a blur on the Overlay layer, and/or a curves adjustment untill you like it. You can also use the opacity of the layer to fine tune.
