Your M22s look like they will be spaced about 10 feet apart. If you plan on listening in stereo, you should strive to place your seating location 8.5 feet away from the centre speaker to create an equilateral triangle. That may put you too close to the screen though. So you may want to place your seating area further away and move your M22s closer to you when you listen to music in stereo.
Also make sure that your M22s are not placed equidistant from the sides and front wall. And experiment with toe-in to get the optimum imaging for stereo listening.
It looks like a nice room. Great job by the way!
