Pixel art game art tileset speed paint in Aseprite - Internal stairs

In this speed paint I fixed some errors with the floor and ceiling tiles that allowed me to add different height rooms. Although, it is not a platforming challenge style game. I would still like to add variation in the vertical space when possible/appropriate.
I was working with the 'Duel' pallet which can be found at: lospec.com/pal...
