Good stuff - I was at the bottom where the river meets the loch the other week, canoeing.
I like the composition of this, great balance. The rocks in the foreground have plenty of interest and the lines of the mountain sides then draw the eye down to the river. The only possible negative is the somewhat negative space in the top left, maybe it just seems quite dark but not sure what you could do about that.
Sorry if you were not looking for any comments but I liked it and got typing.
