ok darlin a couple of suggestions!
first...you need a better song...but if you were going to go with that song u should change the hue and colour control of the clips to match the tempo/tone/mood of the song...it makes a huge diff kays!
second..whatever song you ever choose...match the beats to the landing of each trick or the beginning of each trick and if u can, do both! to do this u just look at the sound waves and match the movement to parts in which the waves peak!
thiiird... dont show so much of the skiing up to the tricks but rather cut to just before the trick begins.
do those three things and your editing will be hot!!!
