Gorgeous photographs - wonderful vision and technique at a truly magical time. Great diagonals, lovely texture. All three images are very tactile.
If I had to choose between 1 and 2, I would choose #1. While I prefer the colour palette of #2, I'm drawn to the subtle, but stronger composition of #1. In #2 there is small group of defined stones that are too centred for me. My eye is drawn to them because they are so defined, but it's drawn to the centre which, compositionally leaves me in the middle rather than being drawn through the scene. Whereas in #1, that same group of stones, being left of centre, invites my eye to then explore left to right through the scene. To my eyes, being off-centre creates more movement; it's more dynamic. Subtle, but apparent if only a subliminal level.
Image 3 is equally beautiful. A slight crop of the left and slightly more to the right side would make the photograph more square and may strengthen the dynamic between the three large rocks. As it is, I find my eye wandering into the right becoming slightly "lost".
