Hi Diogo!!
Wow, that is really looking good and overall you've got it.
There are two observations I'll make (can't leave well enough alone can I ?
)
First, your bow hand fingers are moving around and don't seem to be the same for each shot. Try to set that hand in a fingers relaxed position at your set position and then don't "wiggle" them around as you draw. That will help keep tension out of your bow forearm.
Second, watch your string hand at release. See it pop out and down? Your entire draw sequence is VERY GOOD! Your anchor and transfer are excellent too. Where you loose it a little is in the "expand" step. Your hand moving out and down tells me that you are stopping after transfer and not continuing into expansion. Expansion is called an "internal" movement and cannot be seen - especially with the jacket on. What it is though, is a very small movement that causes your chest (sternum) to move out toward the camera JUST A LITTLE. This is done at the same time as you begin the relaxing of the string fingers for release. I believe that if you can get that movement going, you will find your hand moving straight back along your cheek/jaw rather than out as it is doing now.
This is not an easy thing to master -- it takes some practice. But it will pay off with a cleaner release and help keep everything in alignment with the forces generated. The speed and direction of your current "pop" needs to be redirected to straight back along your cheek.
As I said, what you are doing is excellent and what I'm suggesting above is just trying to refine your shot JUST A LITTLE. Get that string hand moving straight back from the arrow line and you will have it mastered.
