Looks like fun but challenging trailriding there. You are doing well. Video looks pretty good, Utube compresses imagery so you will lose some resolution I hear. TW doesn't have suspension to really perform well in the rolling whoops. Best I can suggest is hover over bike and let it pitch and rock while you ease motion with elbows and knees absorbing motion. Ride more to gain experience. Try to hit downed logs as close to perpendicular as possible.
