The thing that makes this tank look very good is the health and variety of the plants. It just needs some trimming here and there, and maybe some rocks/wood IMO. I'd either keep a few open spaces here and there or one giant open space that's not completely "bald" but not full of plants either. If I'm not making any sense, please keep it the way it is, it looks awesome!! Please add some info- I want MY plants to look like that! :D
