Very cool - welcome to REC diegocasmo!
We're obviously giving you 'pro tips' here as you pretty much master this difficult lesson.
I also reacted on the finger movement which might be a bit big - however when done for the right reason, I think it is acceptable:
I would personally advise you try play to this one at a slower tempo without any picking at all. And this will require more from your legato technique. I always practice this way when I have something technically difficult to learn, it seems to add an additional layer of comfort and tone - which is exactly what you need in the beginning of this track, to perfect the timing.
However even if you are striving for a powerful left-hand-only technique, you should also strive to minimize and relax your left hand motions as you progress.
