Nice composition. I would have metered for the trees a little more, to bring out their rich colors. A polarizing filter would have been good to bring out the sky and clouds a little more. If you did use one, I would have rotated it a little more.
The sky is too light, the hillside too dark. a neutral density filter (or advanced editing) can fix this. Not a real exciting compostion - lacks a point of interest/focus.
this seems to be underexposed, the color of the trees could be brighter, thers really no object to this photo except to show us this mountain, which is beutifull but the exposure is off. what would have maybe been better would have been to get the mountain on the left side and praire on the right and show us both of the landscapes.
