I'm a rookie but ...
If you were able to take the same photo at a different time of day, I think it would be much better.
The exposure on the right is blown out some what, and you have no light on the left.
It looks like there is some nice colors there in the stones, but I'm not sure you have your subject well defined. Maybe have more of the river, in the whole forgroung and not as much of the bank on the left. ?
