I would watch your heels while jumping, they look like they are up. I'd also like to see you release a tad more when jumping. Your hands also look like they are too low. This tends to throw you off balance so pick up your hands a little. You look pretty good other than that, I believe.
EDIT: I'm not sure if the third picture is the one you were talking about. If it isn't, I would watch making a turn like that. Also it looks like you're drawing your hand WAY back. One of my instuctors once told me that "You kind of have to turn secretly", if that makes any sense to you! I know that on some horses and in some situations it's impossible to make the eensy barely-moving-the-hand turns, but I feel that this much movement just brings bad things for the horse and rider. I think that some may disagree with me on this point though.
