well the best way to improve is to keep hittin jumps. always push your comfort zone too. if u wana get better, keep tryin new things, hurtin urself temporarily, then go back and master those tricks.
If anything else, practice hitting the jump and tucking up mid-air so u dont flail. it looks much more stylie too ;-)
at ur doing is good just add a litle like start putting some crosses and grabs in and u will be gravy and don't try and force it to like the it will look really sketchy
I have never seen more steeze off of a jump then that there son...keep the good work up u Texan and send in more footage of yourself to the site plz....
my suggestion is to start ski racing and do that for like 3 or 4 years and freeski on ur off days and ull be really fuckin good dude trust me..... people like seth morrison and shane mcConkey ski raced for like 7 years. good luck
