Feels a little flat imo.
Nice , i like it . But it is missing the WOW !!!
and looks a bit dull
some localized areas of higher contrast …
a few “sparkles” from the rock faces would do
The mountains could use some work, the look like piles of dirt right now 
Especially the closer ones.
I like quiet places like this, but I would give more sun to the cottage and some ripples on the water surface.
Excellent Job!
