These are great! The one with the backlighting and the silouettes is stunning, but there are several outstanding images in this series. I find them very appealing both as a photographer and as a mountaineer. Regarding the climbers, those mixed conditions are quite tricky, and the photograph does a perfect job of describing the activity and the environment, another stunner!
Congratulations on making the top, the time I was there I couldn't tackle it because of the weather, I long to go back (not just to Ben Nevis but to Scotland in general).
All I can add is that I've enjoyed these photographs a lot, thank you for sharing them (also that lens of yours seems like a great performer
).
