I know it's not the best pic and I hope it shows up large enough, but I would like a critique on both horse and rider in this picture please.
It looks like there is quite a bit of resistance involved in your hands and the horse's front end. He's definitely tracking up under himself but he's carrying himself like a banana.
Try more transitions and figures to get him to come down and actually work. Your leg is slightly front of you, which may be ok for what you want to do but you'll feel more balanced and in control if it's a little bit farther back.
You are doing a good job of looking where you're going but try lifting your chin a little more and rolling your shoulders back and down, bearing your chest so you have more control with your core of your arms and seat.
