Nicely done! I think Andy Goldsworthy would approve!
In this case, I think Ma Nature beat Andy to the punch.
Gorgeous composition Nat. I love the tension and balance of the shapes. My only possible nit with what I'm seeing on the web is that I would love just a bit more shadow values in the rocks in the lower part of the image.
It's probably a lot easier to tell in a larger image, but I'm having a hard time nailing down the scale of this. How big are these? Bowling ball size?
Thanks for sharing this, Nat. Is there a coffee table book in the works?
