Love the sun and the blend of dirt and sky, but why do you choose to disorient the viewer by tilting the camera, Xin?
This would might have been a powerful statement about how erosion threatens our National Parks, what with the blazing sun and parched earth, but the use of form (the tilt) for the sake of effect gets in the way of the message.
I hope you shot more here, and can post one that lets nature speak for itself without the disoriented perspective.
