The film was certainly dramatic! I found some repetition, which could have the needed shortening. Also, the jump cuts could have been changed to cross/dissolves. The best part for me was the dramatic high mountain scenes of the last 1/3rd of the film. You certainly bit off a really long hike! Music selection was appropriate for the last third, but at the beginning, something more melodic would have been better. By cutting the repeated shots, you could have shortened it to 3 minutes without losing anything.
Hope this is not too critical for you.
