Looks like an ACjt rupture but would need to do a physical assessment to be sure. It can be confirmed with an x-ray but that's not really needed. A complete rupture that is 'new' could heal with the aid of a screw from the collar bone to the acromion. Unfortunately left as it is (without surgical intervention) it will not heal and you will always have that step deformity.

Looking at your posture generally you seem to be a little lax in that area bilaterally. So maybe it is not a complete rupture but it does look like it.
