I'd put a stepping stone path of some sort and fill in between the stones with a steppable, such as thyme. I put a bench at the end. I'd then fill in with perennials and annuals. Also, include some container gardening possibly in nice decorative pots.
Again, I'd put a stepping stone path. I can't tell if there is a fence behind the greenery, but if there is, I'd put a lattice or some type of support and put a climbing rose or vine. Then I'd place a bird bath of some type in the front. Again, I'd fill in with perennials and annuals.
