Why do you leave the root bone in place. Wouldn't it be better to move it along with the character, especially if you want to continue the animation later with "walking away"?
You could animate the jump section by moving the Root control. You just need to be aware of the counter animation that you need to do.
Say if you want the Head to go higher at the apex, but the feet are in the right spot. You then need to decide how to do that.
Do you animate the Root higher, then lower the feet to keep them in the same spot?
This might lead to a situation where you have animation on the Torso (for the height of the jump) as well as animation on the Root control for the jump. That means you now have 2 things that need to tweak to adjust the animation.
So maybe then you only do the left to right translation with the Root and leave the rest of the animation on the other controls.
This will be up to you.
There are endless variations you could do, but just try to make it work for you.
If your character was going to walk off at the end (and you wanted to use a cycle for that)
You are probably better off to start with the Root control in the position where the walk starts, and then shift the rest of the character back to the starting point on the first pillar.
Hope that helps.
