In the first photo you can see the classic division into foreground, midground and background. In the foreground, moss carpets have been planted, in the midground we have a piece of driftwood, and in the background there is a group of stem plants consisting of Limnophila sessiliflora. These three layers do not create a very strong sense of depth, the layout looks more or less two-dimensional.
