I'm not a big fan of "stuff that isn't normally there" in landscape images so take this with that in mind:
(1) I see two things I don't like here. One is the bag on the rock and the other is the curving horizon. My guess is the horizon problem is a lens artifact plus the act of combining the images has probably made it seem worse. I've seen it happen with wide angle lenses (like 14mm not 35mm) but the algorithm that Photoshop uses seems to negate it for the most part.
Sotol Vista is a tough place to shoot at sunset without filters but that said- you can get something a little more unique if you walk out a little distance from the parking lot.
(2) I like the Santa Elena shot except that it looks like the camera was pointed up. Lord knows I've done that far too many times.
(3) Not digging the power pole in the lower left corner but that might just be me...
(4) There's some kind of band running through the upper middle of the image. Other than that I like it.
(5) Too close to the parking lot. I've been there a bunch so maybe that's not so obvious to most people. Also- Sotol Vista doesn't lend itself to sunrise shots unless it's cloudy (cloudy not clouded over). Maybe wait a little later in the morning and try getting the sunlight washing over the landscape in the distance? I don't know. I have never been there at sunrise. There's also some banding going on in this one
(6) I like this one. Person and all

The sun looks like it was pretty high so probably not the optimum time of day to shoot but I still like it.
(7) I'd whack the cars and buildings out of this one.
(8) Burro Mesa Pouroff is tough to shoot imho. The over exposure at the top and cutting off of the bottom kind of messes this shot up for me. Plus the camera seems to be pointed up and tilted a little (though I don't know how you could ever keep pointing up from happening. It's not like there's a lot of uncluttered room to move back and there sure isn't a JLG lift available to lift you up and down.)
(9) Lots of camera tilt on this one plus it's taken from the edge of the road.
