See that point... On the paving...the one that sends your eye out towards the road? (Not that (that) is a bad thing)
Maybe what you are missing is color ...or a different texture....you've a modern ground choice with that paver...how about one of these -- the colored glaze and then potted to your taste sitting riight on that point or near abouts.
Or a small curved iron bench suited for 1 and1/2.
Both should be clean/ modern/ spare I think because of the paver choice
