The plantings are very lush and the combination of plant species and textures is perfect. However, I feel that the midground area is unclear and weak. The Anubias barteri var. nana are absolutely dwarfed by the sharp, homogenous incline of Rotala rotundifolia 'Green'.
The use of the soft textured Rotala sp Nanjenshan toward the back was very clever. This aquarium shows good use of planting gradients, where you can increase depth by planting a larger species toward the front and phase it out to a similar looking but more finely textured species toward the back. Heteranthera zosterifolia --> Rotala rotundifolia 'Green' --> Rotala sp. 'Nanjenshan' is a good example.
I feel that the stems of Ludwigia 'Pantanal' in the upper left hand corner could be brought out a little more to balance the vibrant stand of R. wallichii.
