The background and the foreground of Grass Room from Maridia in Super Metroid.
I discussed this with you in PM, but I'll put the list here too for transparency sake since it's getting rejected for now.
-The Map16, specifically for the foreground is quite disorganized and would be difficult to use
-The Palette could be shrunk down to only use two rows, one for the BG and one for the FG, closer to how the original game handled it.
In addition to the tiles from other areas of grassy Maridia that could be added. I hope in the future you have time to come back to this one because I think the maridia sandy/grassy area would be a pretty good tileset to have in our section.
