One thing i found neat about ChatGPT DALLE-3 is that it's usually generated via prompts like yours. "a cool treehouse" actually used "Oil painting of an old-fashioned treehouse in a serene autumn setting. The tree's golden leaves provide a canopy for the cozy wooden hut with a thatched roof. A ladder leans against the tree, and children play below, collecting fallen leaves." as the prompt.

Furthermore, i found it's very easy to tweak the general design. A cool image, copy the prompt, tell it to make it more X with Y and Z, and you start producing a really neat prompt.

So far as someone with a lack of mind-image but who enjoys creating computer graphics (3d, animation mostly) it's proven as a really neat test bed. Hallucinations are almost a feature in this to me, granted these aren't strictly that - just saying i find it's RNG flavor over my prompt is really nice for exploring.

Sidenote, i entered your text - looks great!
