I'm guessing by original, you mean the old 8.
Fluorite, Bonfire, and Lonely Cave make me think of an african island.
Temple of Dreams... Herm. Greece-esque area?
Original Ficho and Last Cave, anywhere really where there are caves.
South Pole and Atlantis are...pretty self explanatory lol
Ascension and Sky's Rim, taking away their anti-gravity aspects, I have no clue honestly xD
