I think you are still having issues with the folding of the hip. Your balance is up over the pommel of your saddle in each picture and you lay on your hands, allowing them to balance you instead of wrapping your leg down around your horse. Essentially you are still jumping ahead. If you are doing this on approach, it could also be the underlying cause of your refusals. He's thinking ... "ehh I don't like those" and you are not there to support and drive him forward.
Work on riding in your halfseat, sinking your weight down and around. Once you feel comfortable that your leg wont move, add pole and eventually a grid, allowing your hand to follow your horse's mouth over fences and letting his effort close your hip down.
Your horse jumps a little flat and is lazy with his front end. He really isn't using his shoulder, just folding his legs. It's not a big deal now, but when the fences go up it will cause him to put in extra effort or start hitting rails with his knees (very dangerous). You can encourage proper jumping form with bounces that make him stretch to use his shoulder and making sure he is approaching fences in an active gate working on his hind end.
If your horse says no, you either asked the wrong question or asked the question wrong
And God took a handful of southerly wind, blew His breath over it and created the horse
