I have another question: Can you make this kind of loop with a big kite let's say a 13m North Evo?
Sure can be done, but harder on a big kite, since they are slower. But if you get the height and loop aggressive enough it works.
A small kite really helps, and makes it more fun, faster, safer and easier. Even Lenten prefer smaller kites for looping. I hardly loop at all on bigger than 9-10, it´s not as fun, prefer unhooked on bigger sizes.
Next time I will use a kite one size smaller with a bigger board and loop it a bit earlier.
Going full speed really helps as well. The faster you go, the higher you go, an the easier it will be to get the kite around and up to catch you again. If you go fast you can still go high without being to much powered and get to much in the loop in the beginning.
Also try looping aggressively, steer the kite as hard as you can. And holding a wide grip (not narrow like for unhooked) will help this.
