Hi Josue,
Your posture looks good!
I think I see two things you can improve though:
1) your stance seem to be a bit narrow. i.e. if you bring your back foot directly forward, it should land shoulder width from the left foot. Jesse calls that the "channel" between the feet. From the picture, it seems your right heel is on the same line as your left foot. Move your right foot 25-30cm to the right: the stance will feel more comfortable and you will be able to relax the hip even more.
2) bend your right arm a bit more by dropping the elbow a bit, it will allow to relax shoulder and wrist a bit more.
Static posture work is good. You should be able to meditate few minutes in every posture

This means that you have to find in every posture how to relax hip, shoulders, arms, etc, while keeping a good intent.
Not always easy to explain things with a keyboard

Try these changes, see what works for you.
Hope that helps!
