The "Just left of center" positioning feels off.

Ideally you'd be well off center (rule of thirds). I feel like proper center would be better here. I crudely cropped it (ie: held my hand over the right hand side of the picture) just past the triangle (diamond w/ reflection), and preferred it. I could also be that the bright log to the right pulls the eye away, and I'm cropping that. Everything else over there is very dark, so I'm not really losing content, removing a distraction, and improving horizontal symmetry.
