I really love #3... super-cool.
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.
