Need help choosing a photo album cover.

I went out to Drumheller in Alberta last weekend and got a nice set of landscapes, a few at the Tyrrel museum and a couple of the town itself that I'm happy with but I need help deciding on the Album cover for the set. I arrange my shots into albums then upload them to facebook, flickr, send them to friends..ect and have one photo that I take during the day dedicated to the cover shot but I just cant decide which pic to go with. Does the blue in the sky in #2 look forced? Any suggestions would be great!

I like number 1 the best, 2nd one has a weird gradient in the sky. I would however ease up on the saturation a bit with the legs in number 1.
