first 180,…

I just started snowboarding this december, and I spent the first month of snowboarding carving and stuff, but yesterday I just built a little jump in my backyard and attempted a 180, I fell the first time but the second time i landed it. So I would want to know what I can do to improve my 180 and just my snowboarding in general. http://www.youtube.com/watch?v=zK3v7qGdBZA
