AI understands proximity of things in 2 dimensions. Convex structures are easily projected on flat surfaces. Blobs are convex structures. Boobs are blobs.
My first prompt was "floating cities with agriculture"
"floating cities" => it was too dystopian. Very artificial squared islands with tons of buildings. So I reversed it to "towns on floating islands" to enhance natural looking islands.
Without "palms" and "solar pannels" => it was like floating getthos. I added "palms" and "solar pannels" to make it paradisiac and futuristic.
Resulting prompt (Dall-e3) : "sea covered with towns on floating islands, palms, solar pannels, agriculture"
It's way more practical than a Tesla. Whatever, the Berlingo model now starts at 39.000€ (EV only). That's twice the price I bought mine. My salary has not doubled in 10 years.
About the black line ? It's not an "error". After the filament being changed and purged, the nozzle traveled on the surface of the white part. By travelling, ot wiped itself on the surface of the white part. It's not a traced line. It's a thin line of wiped black.
However I could correct this by setting the park location near the seem or by adding a non null zhop (having the head to jump instead of wiping itself).
The knight is "Don Quichotte". "Quexotic" / "Quichotte". Good enough...
