June 25th Part 3 video- Your posting looks very forced and you are landing harshly in the saddle. Your arms are moving with your posting- back and forth, back and forth.
I do commend you for being able to pop right up and into the correct diagonal, if not then being able to catch it pretty quickly. I'm also glad to see that you are doing lots of transitions.
I haven't been reading any of the other posts, so idk if what i'm saying has been said already or not. I would like to see his head being more steady in the bridle and not popping up and down, although with your quieter hands and arms I'm noticing it less than in your videos from however long ago.
Next step is so you don't have the following problem, "When my inside hand goes in and it looks like I'm pulling I'm not". Work on making your cues much more subtle so you don't have to defend yourself.
I look forward to seeing you progress, you have a handsome horse and you certainly have the build to become a very elegant rider. If i'm being too harsh or you don't understand, please tell me.
