Sure! I don't mind at all Chris!
It's a funny thing about the extra tilesets. When I went through the palette swaps in Hyrule Magic...it seemed there was an extra 2 palette sets. Color swaps 48 and 55. Unfortunately, only the walls and some of the floors had any usable colors to them, so I decided to use those color schemes, and ADT 17 and ADT 18 were born. Of course, the furniture, decorations, floors, water, and ice all had unusual colors for their palettes, so I improvised and added those in myself, using what I believed would look the best with each color scheme.
19 was something I was experimenting with on a whim. I actually took inspiration from none other than metalZelda himself. His video of the Water Temple in his game inspired me to make a blue colored tileset myself. the greenish colors were, in my opinion, done to kind of give the whole scheme a 'seaweed' feel to it overall, and I feel like it turned out beautifully
Plus, if i'm going to sound a little biased on this, blue is my favorite color
20 is a special case. As you know, each of the tilesets had an unusual dungeon wall pattern added to it--it was hard not to notice it. That would be inside jabu-jabu. For those who don't know, 13 years ago, I began work on my own Zelda fan game. it was titled "The triforce trials", and never made it very far in production. I included a screenshot of Link standing in the triforce temple as he is about to obtain the master Sword for the first time.
Around mid 2005, I started having real world issues and had to put the project on hold, as back then I was an active member of the Zelda Fan Game Central forums. My game was noted as "the most anticipated fan game of 2005". Unfortunately due to my priorities (fatherhood among many), forced me to abandon the project. I was a friend of Antony A. brown (aka "aab"), and he too was working on a few Zelda fan gae projects himself, most notibly, "The Spirit World" (I think that's what the name was.
At any rate, He and I talked a lot, and eventually I saw a screenshot of a project he was working on for his game...it showed Link inside jabu-Jabu...LttP-styled:
It looked amazing, so I asked him if he could share the tileset with me....and this was what I got:
I've had these two sheets in my hard drive for over 10 years, and although I lost literally ALL my project's work, including the backups, this may as well be all I have left, so I ripped the basic wall patterns out, and added them all to my tilesets. Then I figured, since I had 19 other tilesets to work with, I may as well color a 20th scheme after aab's not well-known tileset, Jabu jabu, and ADT 20 was born:
