Preferences for tiles used in Roll20

I'm working on some tilesets that I plan on submitting to the Roll20 marketplace when they're done. My experience mainly comes from working with tiles for programs like RPGmaker, so I would be making tiles that are meant to interconnect in squares like using tiles from the Tile E in RPGMaker VX (which I have most experience with) or any of the tiles in older versions (like XP and 2000) But my question lies in how people prefer to tile. Do you prefer to lay out your floorplan where each tile is floor and wall/construction obstacles? OR do you prefer to just tile in the floor and then build the walls on over it? Also since I'm curious as to how people might receive my tiles, here's a sample of what I've been working on and I would appreciate opinions and suggestions of things to add. I plan on also making building tiles that would be in the perspective of an RPG game that you can have a building overtop of a floorplan if you wanted, or it could all just be an outdoor map. I plan on doing a full set of tiles (first a wooden set, then a stone set, MAYBE an outdoor/wilderness set) So please tell me what kind of tiles you like to use and why.

If these are all 1 tile=1 sq then I see a lot of repeats. If not, can you tell us where the splits are. Overall quality looks fairly good, assuming final tunings and refinement have yet to occur.

Each grid square is one tile. If you mean repeats by tile rotation, perhaps, I have not taken that in consideration much due to the nature of the tile pattern, the walls and doors are still a work in progress As for the Bridge, that is meant to be one construction, moreso than tile by tile right now.
