Was decent riding considering your age, but I have to agree with extremo. Work on style, especially on those spins.
Honest but harsh opinion: I'd rather have seen a 180 grabbed with style then the snowboard spins in the video featuring the wacky waving inflatable arm flailing tubeman.
If you need to just film 180s and 360s to have style, then do it. No sense including clips of really hucked spins with no style. Style > spin count.
