As it says in one of the need for speed games "Leane back, lean back, LEAN BACK !". Chill out abit more on't backwheel. Trials isnt a rush. Take your time.Try and sit on the backwheel when riding basically. I used to be very similar to you back in the day. But a few mates pointed out that i was far to far over the front, told me too watch a few video's and they'd also help me out. In around 2 weeks my riding style changed completly when doing everything. Also my riding progressed quite alot. So, Chill out on back wheel. Relax the arms. Take your time. Maybe tilt your bars back and maybe a higher stem but im sure you can re-adjust your style to the current set up you have. If i happen to come on a ride that your on for some reason. I'll spend some time helping you out. I mean im no pro. But i'll do my best. Good luck man. Danny.
