#2 is a bit tilted CCW, but I like these very much! I think #1 is my favorite. Oregon is one of the 4 states I have yet to visit and this really whets my appetite!
I'm feeling like maybe you were wishing you had a wider angle lens? A couple of these feel a bit too tight in the field of view, but that may just be me. When I'm caught wanting to shoot something wide and only have, say my 70-300 with me, I shoot a few pics and have Photoshop stitch them together afterward. I've only done it a handful of times but it works pretty darn well.
Really like your pics, as always, thanks for sharing.
Nice pics always remember one rule, never have a line going through the middle of the picture. Always 1/3 or 2/3. Either have 1/3 or 2/3 filled with sky and the rest landscape or the other way around. That's what I learned yesterday. Perhaps on the 3rd picture, you could have moved the camera up slightly to get more of the sky
