Thanks, I found that 24x spacefox through the forums (and a 24x phoebus too). It's true it scales pretty well thanks to it's cartoony style, but it'd need a lot of clean up to keep it crisp.
However, when I said I wanted to make a new 24x tileset, I wasn't talking about "porting" spacefox to a bigger size, but making a completely new and original 24x tileset (and that tileset is the one that has 5 possible walls variations I have to choose from). Yeah, a bit crazy since I've never done pixel art and I'm a newcomer to playing DF.
With spacefox I just wanted to change some tiles to maintain a bit more consistency (kind of what you did with the plants) and give it it's own tiles where it still uses some from other packs. And the walls
, don't know why but I wanted to change the walls. I intend to do this mainly for me to play, and if anyone likes them maybe you could add another variation tileset like the ones there with the phoebus tracks and so on. I intended to do that as well with animals, objects, creatures, to complete the set. But now that I decided to go for the new tileset I don't know if I'll do that in the short term. I'll complete the basic spacefox tileset though (because I like playing with it, and the other one is a long way till I finish it) then we'll see about the graphic pack.
Some examples of what I have done with spacefox:
These are the tiles I have changed
These are some wall variations
Some different variations for the tiles I've changed (this image is at 2x size)
And this is how it looks "in game", well, sort of because I used DwarfMockup for this and it doesn't use spacefox colors and the walls look a bit wonky but still...
