I dled and not bad for a first man. Your plane skills seem to be pretty cool, now just take em to the ultimate limit, like upside down through gaps that your plane only jsut can fit under. Your bike skills can do with a lot of improvement though, try getting some air 2 grinds, instead of just basica krails and learn to bump and use PB's. REad Deathcobra's guide in the SA Chat And Support section to find out how to do all these stunt techniques. And generally, another pointer in bike stunts is to land on a high roof. So find a high roof, that would need about 50ft + to get on there, and then utilize the stunt techniques to get up onto that roof.
Good luck and thanks for sharing.
