I was inquiring about garden stones, rather than pathway stones. Goes to show I guess, how easily some things are misunderstood.
And,.. I think I begin to understand where you are coming from, so to speak:
I missed the explanation that in your back yard you wished to recreate the idea of a street-scene, the major symmetrical central axis all-inclusive neutral walk to the temple or front entrance gate of a home or restaurant. And this impersonal 'walk quickly corridor' is the main view from the inside of your house, basically, where you are is on the street, looking into someone's garden.
-- and that the 'court-yard' garden you think of, is not in the back yard, rather, is a front entrance garden of the Japanese home or temple, essentially a public place that gives instruction for a visitors method of approach. (and 'courtyard' means different things in different cultures)
Quite intriguing. I recollect a garden in Europe that was a recreation of a small village crossroads: 3 corners of recreated houses with over-hangs, complete with the central 'village gathering place for community drinking water' fountain with basin and a smithy off down a dead-end side lane. Very charming. Especially as one of the houses had a small cafe like setting on the curb pavement.
For improvements then I would suggest that a gate be added,.. though, on which side the water spigot should be is something you need to address.
(personally, and you have not asked for anyones personal thoughts, so I apologize in advance for offering mine:
- as you are insistent on that design, I would flip the garden design so that the entrance way pathway, would be coming from your back alleyway through a gate that would hide the blue tarp,.. this way you could enjoy the water feature from both sides.... but, my suggestion is not valid because it reverses the street scene you are trying to create)
1) I would improve the garden idea by suggesting that you avoid using the stone pathway setting that is in photo # 4 as it is a utility path that is rather dangerous and not very well crafted. (please note it is behind the chozubachi, not the 'best path' that would be in front of the chozubachi.)
2) that you avoid using the tsukubai arrangement in # 6 because it is missing some critical pieces, such as the 'front crouching' stone (etc), and, the Sen Ju Ji lantern should be avoided in such a setting.
3) in the last image, # 8, the first pavement/step stones are poorly set. I'm sure you would improve on that setting with the budget you have dedicated to replace pathway infrastructures, though I see the feelings created by the rest of the courtyard garden that would apply to your ideas.
4) personally, some of the replacement trees you have selected are messier than orange trees because they don't have a harder outer shell that obviates the opportunity for organic Bocce playing, but again, I don't have an orange tree and some people around here spend a lot of money on custom greenhouses to grow orange trees... we all have different values and that is a good thing, as this keeps the world interesting. happy holidays.. best wishes to you and yours..
