In reply to ori:
Some nice shots there. Personally I think I would dispense with the footage taken from the selfie stick - it looks huge and out of proportion to the scene, a bit like a ski tow T bar in the way! As cameraman, just concentrate on filming the other two.
Also I think live sound would have been better at catching the atmosphere rather than the music. Music seems to be creeping into such filming more and more now, and I think picking up the natural sounds of ice creaking under the crampons and axes, the wind and talking at times is much better, interspersed with a bit of commentary by you.
But generally I enjoyed watching it. Good sense of exposure on the snow ridge.
