Your edging looks good... but I'm no expert coach. You're holding it all the way through the wake for the most part which is a good thing, and you've also got the nice progressive cut going on. The 180 isn't all that difficult of a trick. Just remember to pop with your legs to get some height, and rotate at the apex of your jump. Let go with your rear hand and try to land slightly on your toes and contiue to edge out on your toes. And BTW that water wasn't too shabby for a big ol' lake like Erie
