I agree - I think you've got a little bit of separation/recirculation right around the center mounted brake light.

Most of the time the tufts are sitting relatively still, but every once in a while you see one going sideways & backward.

To me, it looks pretty good. Recirculation/locked vortex is much more evident on the back window of an '07 Civic or '06 Corolla that I tuft tested:
