Nice shots! I really like the stress line through the ram's eye. Only one of mine has that.
A nice planting of stems down the middle, kept thick and about mid height would look nice.
yeh, I'm thinking of taking the clips from the water sprite and lining it down the middle and move the blyxa to outer edges. Maybe take the alternanthera and put it in the middle as well giving some contrast the the water sprite. The water sprite is doing really well now that the BGA is gone.
