good job on hte photos, but ur riding needs some work :-P
in those corners, slide up towards the gas cap, and lean forward on the bars a little, and use the gas to swing ur back end around. On the jump, u look rly up tight, u just gotta relax, and it sounds dumb but just get ur head out of the game, and just think about going as fast as u can, not how ur going to do it. I'm not trying to be mean or anything, im just saying this to try to help you out so u can get fast, and maybe get into some races.
