Good job!!
For more indepence you could put your treats behind the weavepoles, on a chair or something like that. When you have him go through the poles, run towards your treats and treat him.
You are already doing this, but now you are running back to the camera. By putting your treats in line with the poles you create more drive.
Also, try to stay upright and decrease your movement. Now you are still moving in and out with him. I make a sound all the way through the poles, like ssshhhhhhhhhh or I clap my hands(depending on weather I am out off breath or not

) This helps my dog to keep going.
Something else you can start doing is, to slowly increase the distance from your dog. Keep running next to him, but take a step to the side.
