Isn't that great of a critiquing picture, but I'll try
It looks like your a tad bit ahead of him. Your knees are pinching, causing your lower leg to totally loose it. Your lower legs are too far back, there is no weight in your heels, and your toes are pointed out. If you just opened up your knee and griped with your calf, your lower leg would improve 110%.
It also looks like you have chicken wings .Also you need just a liitttllle bit more of a release.
That's what I could pick up, it's hard to tell since it's dark and small.
He's a cute little jumper! You guys make a great team.
