I think that your aquarium must be lovely. Lots of real plants and an interesting rock, is it centrally located or off to the side (that's always more artistic if you put a show piece off to one side)? The only thing that I would advise is: you need to have fish for the top of the water and the middle zone, and the bottom dwellers. If you add some floating plants, you'll get that nice green tinge to the light and shafts of light will dance on the bottom. It looks like you might need a nice corydora or kuhli loaches. Maybe some rosy barbs, I love those, they're not as fiesty as the tiger barb. But really, your aquarium sounds very nice. Sincerely, Carplady
