Second image could have used some artifice having been employed, areas of the clouds are blown out. Sparky already mentioned the distortion.
IMO landscapes can't just be photos of "landscapes" to be decent photos. You need to demonstrate an interesting subject or theme in a great landscape photo, and thats what makes them so difficult. When done "right" your taking the widest perspective possible, and yet still drawing focus to a specific subject.
Keep shootin!
