Surround Speaker Placement Advise (with pictures)

After a lot od thought I decided to puchase the adjustable Sanus speaker stands fie my Sonos One's. Now that I finally have stands, need a little bot of advice for placement. Been on this forum for almost a month and have learned a lot for instance, my couch is against the rear wall is not a desirable listening but really have no choice there.
I've placed the stands at the corner ends of the couch, but not really sure if i should point the speakers inward towards the listening position or firing forward.
Your thoughts? Open to other possibilities also.

Thanks in advance.
