Replying to 360 help please.

Ok, so I recently ALMOST landed my first 360 (as in landed almost finishing the spin and just fell over a little). But here is the problem. I tried it 2 more times, and wiped out on both. You know how when you go off the jump, your body is at an incline facing up diagonally?? Well, after I finish the spin, my body is still in that incline and I fall because of that, landing on the back of my skis or my ass.... So, how can I make sure I land straight?? Note: I lead with my head, I know that much.... So can anyone help me out here? Thanks a lot....
