Oh my, that's a lot of work, even before you get the plants in! Rounded field stone is more difficult to work with and make look nice. You did a good job!
Leftwood - thanks.. yeah they're tons of work there.. I had dirty shirts everyday earlier this year LOL..
Pudge - It get about 3-4 hours in the afternoon.. not great but its not bad either being in Maine.. our summer is not as intense as down South and I'm still looking to plant some small trees around the circle and to shade the small tiny gardens nested on the rocks...
