To be honest, I'm having trouble finding your focal point here. The rocks look blurry, but maybe you are focused on infinity. Without EXIF I can't tell what your DOF is like.
Scrolling back up to the uncropped image, it looks sharper . . . Hmmmm
colours are superb, but not sure if it is sharp on the rocks...could just be the crop though, and yes, agree, crop more from the bottom...put the rocks on the third.
