It's not a stupid thought at all, in fact you may have point...I'm not at all sure myself. But I'm experimenting and learning all the time and the scape is definitely a work in progress. I've already moved some plants around since the last image was taken. The fact that the water was very murky, casting much of the scape in shadow doesn't help either. That said though, I suppose for me the plants are the main interest, and the hardscape just the framework, but I'm sure other's, like yourself, will have a different perspective...
Either way thanks for showing enough interest to pass comment🙂
