Nicely done contours =) I like how you executed the plantings too. Are you still planning on adding marsela in the top right corner? If not, maybe consider letting the micro swords fill into the upper left corner and transplant the s. repens in that corner to the right?
Looks really great either way... just can't help but see micro swords in that corner. The moss looks good trimmed in between the stones too.
I haven't decided just yet what I'm going to do in that corner. I have Hemianthus (Micranthemum) micranthemoides, Stargrass, and Giant baby tears coming in on Monday to work with. I also have plenty of runners to snip from the 12g of the MM, so we shall see what I decide to do.
