I would have to check the name just to make sure. There is substrate about 1.5cm thick under the gravel. And gravel 2cm about. CO2 canister and regulator with a DIY bubble counter.

what is that plant on the left hand side, it looks like purple waffle? and the plant in the middle with the skinny purple leaves, looks like dragon tongue? both of those are non aquatic, and will die off under water...
They'd probably look really good in someone's emersed setup. Maybe you can swap them for something more suitable?
some live up to two years, they do "better" in colder water but will still never grow totally submersed, you can take them out plant them and keep putting cuttings in your tank if you want some extra color really desperately, but with CO2 there are much nicer aquatic plants you could be growing instead.
