I really like the tileset and think that it will be very nice for your game, but the floor is always really hard because you need something that has more then one color and it loops, tiles are easy but carpets are really hard, i'd suggest studying the shadings of the rtp carpet in your spare time, other then the carpet I would definately play your game :grin:
I'd ask you to start on the collection of the tilesets but then I'd feel guilty about overworking you when you finish this or feel like starting the work I have planned feel free to pm me :grin:
Thank you and have a happy holiday!
