A single large-scale object always makes a bigger splash than a cluster of small objects. That's obvious here, where the saucer-shape water feature dominates (but doesn't overwhelm) this Spanish-style courtyard. Its dimensions are practically the same as the arches across the loggia, unifying the water feature with its surroundings.
I like the dog pool! I wonder if that's just a plain terra cotta pot. Kind of looks like it is. It's just a warm look. I can see some pretty cushions on the furniture. The plantings add a lot of ambiance, not sure how welcoming this area is though.
