That last FTS looks great! The hill, rocks and HC have come together nicely. The Blyxa on the left flows really nice as well, but the stems in the back are taking away the hill look IMO. Maybe it's the way they are cut or maybe it's just the stems. Some downoi crowns would look better IMO. Either way, nicely done!
How are your trees doing? My trident just started to change colors and is loosing a few leaves.
