Looks great to me, a look I like.
Consult locally re whether the pavers are best set on mortar so they don't mush around and up and down. You can set on mortar and still leave spaces in between for planting. That's mortar, not actual concrete.. Real stone of much more thickness moves around less, but costs a lot.
Weeds do come up between the pavers (one thing in favor of a real concrete slab). Slabs tend to be 3 1/2" deep and may have rebar in them if you live in earthquake country, and should have proper expansion joints and scorelines. They can also be broken up with spaces, say, 8 x 8 ft slabs (+ scorelines) with several inches in between.
Another choice in LA, and somewhat used by us in Humboldt county, was to recycle broken concrete into good sized pavers (instant old look) setting with or without mortar under and between. I'll dig up a photo if you're interested.
With the pavers you're showing (architectural slabs, I chuckle - but maybe they are thicker than they look, and I have been presuming wrong), you can change your mind, move them around into different patterns. Plus, less money as an investment, I presume. That greyish plant between the pavers looks like woolly thyme, which is what I used and worked well; I mostly had woolly thyme, but also placed some others of the low growing type (elfin thyme, and some names I forget now).
edit - I should have just asked how thick they are...
