As requested (keep in mind these are my opinions and are highly subjective):
The bad:
1. The bottom left corner, I would crop out. It just doesn't belong IMO.
2. The photo is quite grainy. Maybe this was purposely done but a landscape such as this should be noise free (again IMO).
3. If you have a polarizer, you might try using it in a scene like this to reduce some of the haziness in the sky. Haziness isn't really bad here, but it is noticeable in the right portion of the photo where the more distant mountains are.
The good:
1. Lighting and dynamic range here is relatively good. Both, your landscape and the sky are properly exposed and you can even still see the details in the sky. You either waited for a great time of day or you worked your magic in PP, either way, well done in that regard.
2. Great location and good composition (with exception of the lower left corner). Some things that really deter a photographer from making a good photograph is the difficulty of the angle or location. I don't know how much effort you had to go through to get to where you were to shoot this, but you're in a great spot!
