Well I finally was able to check out the vid. Poutanen was right! Hot Shadow!
(...I LIKE shady women!!!!
Seriously tho,.. For 10 days riding? Seems to me you're doing quite good! (...don't think I was riding that well @ 10 days!) As others have pointed out, it's a bit difficult to tell a great deal about your technique from your smokin' shadow!
But I thought I noticed in some areas that it looked like maybe you had your shoulders turned to face downslope while riding straight down the fall line? I thought it looked like it was causing you to tend to turn heelside!? That appeared to be the side you usually "went to" to apply the breaks? Again, hard to tell for sure!
that is the case, you might want to try focusing on keeping your shoulders in better alignment with your board. Use your lead arm to sort of "point" (steer) into your turns!
If I am mistaken about the shoulders,.. then I would say based on the way you're riding now after such a short time on the board,.. It's only a matter of time & practice!!! More time & experience, you will be going faster and with better control before you know it!! You have a distinct advantage over lots of us in the midwest,.. you have much "longer" runs to practice on & that can help you develop the "muscle memory" for you to progress better/faster than we can with our 90 sec. to 2-3 min. long runs!
(...fewer breaks between successes!)
Definitely like to see some follow cam vid when you get the chance! Have fun!
