How big is the tank? You need more plants. Maybe some drift woods to map out the shape of the layout. Right now, is like everything is flat. The stones don't do it for me. Very unnatural. Those cabombas will grow like weeds. The Amazon sword will over take your tank, which is fine if you have it in the corner. Are those micro-swords or dwarf grass? You are supposed to cut them into chumps. Maybe 5 to 8 strands of grass and to spread them out on the substrate. The idea is that they will carpet your entire substrate given with the right condition (CO2, nutrients, and lighting).
