I like 1 and 3 very much. Good shadow detail in 3 requiring some overexposure of the sky, which you nicely kept to a smallish area. Excellent, classical composition suiting a scene like this. 1 is highly dramatic yet realistic, an image you might catch in the blink of an eye in passing. The soft, hazy background really works well. The other two are OK but don't do so much for me.
Although I was camping about 2000' below BRP two weeks ago, the day I decided to get on it, a complete white out...literally couldn't see 10 feet in front of the truck.
Most of the rest of the time was very overcast and I got a lot of sky blow out like in #3. Apart from that critique, nice composition.
I dont have any general critiques for the rest other than the colors seem a little dull. If you werent shooting with a polarizer outside on #3, thats a recommendation. Maybe time of day and a tripod could help with your color saturation. All things to keep in mind. The S curve is always appealing to the eye. Something all landscape architects should know.
