Beautiful scene well captured, nice light too.
You've asked for crit but there's precious little wrong really, it's a lovely natural image.
You could, of course, spike it up a bit and make the absolute most of the colour and light (I've done a mod).
Ignoring the sky for the moment.
Levels are fine.
I made a layer.
Curves, I pushed the centre of the curves up to make a soft C, this lightens the mid tones.
Colour controls, I moved the highlights slider into the yellow (away from the blue). This lightens and brightens the upper end of the mid tones and adds to the light effect in the image.
Saturation, I saturated the greens, reds, and yellows 10.
Dodge and burned the trees and tree shadows.
Now the sky, it's a bit weak and turquoise and lets the image down just a tad, I feel.
Close eye on top layer.
Working on bottom layer, make duplicate layer. Multiply (layers pallet). Merge down.
Open eye on top layer, select sky, erase sky and clouds.
Now go back to bottom layer, Hue/saturation, slide the hue right a bit until you get a better sky colour.
Merge layers and use the blur tool on 3 hard to run over the hill/sky join to get a natural bit of blur on the horizon.
Hope you like it.
