You have excellent visual-spatial ability. I have maladaptive daydreaming disorder, yet struggle to directly visualize.
Sadly, the aspiring architect known as Justus Grossbier is very much impaired:

Have the same problem. Want to do reptile, fish & amphibian keeping.
So far I have neither the money nor the space for it, but I often draw plans beforehand.
And spatially I am so shitty. But I still try and read the literature about it.
I make backwall designs (like rock surfaces with styrofoam/glue/sand) and plant lists (mostly from the natural range) on paper. I also look for good wood/rocks.
My dream is a garden boa, a tiger rat snake, a sipo or other puffer snakes (like
poecilonotus/sulphureus) for a rainforest set-up due to my love for bromeliads, passion flowers and araceans (like anthurium/scindapsus/monstera).
Or some mountain kings like the
zonata/pyromelana with natural rocks, an artifical backwall and some ferns/tillandsias/coniferous needles.
Or for ball pythons sansevierias, zamioculcas, etc.
Or for Perth Pythons/Stimson's pythons/Womas/Blackheads a fake red rock wall resembling the cliffs/creeks of Australian drylands.
My absolute dream would be a rough scaled python, very rare from the Western Australia (Kimberley Region) & some small islands, likes sandstone walls in rainforests, very long teeth for catching rock rats that throw off their fur. It can be kept in a rainforest-like terrarium with a rock wall.
I love Australian lizards too. I particularly like here
Oedura/Saltuarius/Phyllurus and Pilbara monitors.
For aquariums I mostly like Suriname toads/
Pipa sp. and other pipids as well as predatory fish.
So far I have only read books and drew it. But maybe I will do it irl if I have the opportunity. I have spent years with books/documentaries/forums about reptiles/amphibians/fish in nature and saw (and even caught) almost all of them in my country, now I want to keep them.
