You walked up Pen Y Fan (you've a typo in the title) before sunrise - in winter -a madman! The shot would probably benefit from something like a person somewhere in the frame to allow the viewer to better determine scale. Please don't tell me you went up on your own! Beautiful colours. Regards, Gary.
Woops. Typo corrected, thanks Gary. I know what you mean about having a person to give some sense of scale but for some reason nobody else wanted to come with me that morning. I guess I can understand why, it was around -10°C and very windy with a 4am start.
