One of the best ways to create a spectacular aquascape is to enhance the sense of depth and perspective, using hardscape, planting, open spaces and textures.
You have done so in a combination that displays the skill of a master. The hardscape selection and positioning is bold yet naturalistic. A tough balance to achieve. The same goes for the planting.
If I had to point out one distraction - you know what it is... The red stems at the end of the path.
I'm extremely impressed. Thank you for sharing and inspiring.
