Do you want my *slightly* edited version (The normal version does not have these nice white floortiles and the white walls^^)?
Here you go:
Here is the wall autotile (its an edit of the default wall autotile)
And the door: (also edited by me to fit to the tileset)
You won't have to credit me though, as I only made slight changes.
Now, could you give me the tileset you are using? XD (@Aqua)
EDIT: The original tilesets where done by Kiearaphoenix, thanks to RoseSkye for poiting this out.
