This looks incredible! I love the details

This was the Mushroom World from 2 Souls' Tale. You would have started at the bottom center of the map and immediately enter the Mushroom Kingdom. To the left of the MK is Mushroom Way (Goomba King with Red and Blue Goombas would have been here as a boss fight), Koopahari Desert (with an unlockable Sarasa Land represented by a Gameboy there - Totomesu, Dragonzamasu, Hiyoihoi, and Biokinton/Tatanga would have been bosses here), Great Pyramid (bosses would have been Eyerok, Pom Pom, and Fire Bros.) Pipe Land (Mega Smilax would have been here), Vista Hill (Belome would have been here), and Bowser's Keep (which I didn't get around to - it would have had many bosses including the Koopalings, Bowser, Kamek, and Boom Boom). The right showed: Bandit's Way (Croco was here as a boss), Star Hill (which had a hidden Animal Crossing Town area behind a waterfall in there), and Hippo Zone (Wario and Waluigi would have been bosses here in the Second Quest). Space included: Space Zone (Tatanga - rematch - and Watinga would have been bosses here), Astral Observatory (Geno would have tested your skills here in a boss fight before becoming a summon assist), Freezeflame Galaxy (Culex would have been a hidden boss here along with his Crystals), and finally, Second Quest would have culminated in Smithy's Factory (not pictured as I didn't do it) (the bosses there would have been Mack, Bowyer, Yaridovich, Axem Rangers, Countdown, Cloaker, Domino, Mad Adder/Earth Link, Gunyolk and Factory Chief, and Smithy (2 Forms)).

THIS IS AMAZING!

Bowser's Keep (SMRPG version) was going to sit on the mountain on the top left, but I messed up on that area and it was too small and I was too lazy to fix it.
