Yeah! now I know why I looks funny- it is because of my head and arms. Thanks so so much!
BTW, it is my third season (~15days/season).
posture doesnt look to bad to me, if your comfortable in that position then no worries. Only thing I can see is you are leaning you head down a bit much, if you bring your head up a bit it will straighten you out somewhat. And this doesnt have to do with posture as much but if you want to ride more styley, try putting your arms down. You kinda got the surfer thing going on. All in all your transactions look pretty smooth. How long you been riding for?
