I don't have any really quality close ups, but maybe I'll post one if you really want to see the rock close up. It is an really nice piece (the big one). It had exceptional character for this rock type, which we usually don't use for such a focal point (but rather for substrate barriers and general texture with driftwood). Though I do come across some nice pieces and set them aside for such projects as this one.
Tom, here it is glosso and hairgrass.
