First picture: You look pretty centered over your saddle, which is good. :) I like that your looking up and ahead.. Your leg has slipped back a little, and your heel isn't quite down yet. . Er, I could be wrong, but this is just what it looks like to me-- Your release looks
good, but it seems like you are still catching yoru horse in the mouth. I don't really know how to fix this because it looks fine. . We'll just have to see what other posters think!
Can't really tell anything in the second picture. But I like your horses knees!
The third is a bit too small but I like what I can see. :)
You look great in the next picture, but I would like your hands not to rest on his kneck so much :)
In the next few pics... your heal isn't down at all. So yeh, I'd work on that :) and your are looking down in smoe of the pics, too. Make sure you are looking where your going!!!
