A room with a view, obviously ...
I wonder whether you have experimented with the positioning of moving people within the given frame? In this case, perspective is very flat and that in itself lessens the dynamic impact of the image. Do try such captures when the positive element (ie. persons walking in this case) is leaving not entering into the centre of the negative space. You might be surprised of the change in dynamic appearance. Anyway, just try. Rules about "leaving room for movement in the direction of travel" and suchlike phrases of which the textbooks are awash, easily (and dare I say, unknowingly) become constraints rather than helpful suggestions. Break the rules. That is the reason they are there in the first place.
