The edging was was done well on the west curved edge of the patio, but the concrete forms were not laid properly for the straight south edge. First, there was a "pinching in" that looked really wierd. Fortunately, this was (mostly) fixable by trimming some of the straight edge. So while this isn't quite "correct", it is probably the best one can do as visually as the "pinch" isn't as seeable as before since it's stretched out a bit.
The much harder issue is there is a vertical rise above the surface of the ground as it moves to the East. This is a real bummer, since I don't think this is truly fixable. I noticed and discussed this right after the pour with the main guy and he said they would do whatever it took to make be happy. I guess one could shave a few inches off the top of the concrete edging, but this would make it look different, and even if you went all the way around the edging, it would be hard to do well; my experience with a patch on the concrete flower pots isn't too good so far. So the proposed solution was to build up the nearby ground and rocks so that the concrete edging looks like it was always this way. We even had to add another layer of 6x6 wood beams to the window well so everything looked level and correct.
The shame is about about 10 minutes of work pre-concrete-pour would
have caught this, but unfortunately, it ended up being a lot more work
to fix after the fact ... but it came out pretty decent - see the
before/after pictures below.
