Great start with your aquarium! Some information for you, though. Ophiopogon kyoto is a non-aquatic plant. I would take it out of the aquarium and plant it in a pot. Samolus floribundus is also a terrestrial plant, a relative of the primrose. Though it can grow in shallow water, it is a perennial terrestrial plant, that would do best in a shaded location with heavily watered soil. The java fern is a nice specimen and I really like your anubias. But I am especially partial to those. They are in every tank of mine.
