Quite okay but the mapping is awful. First of all you didn't eaven credited proper people for the tiles. Then the characters are missing shadows, well if you prefer it that way okay but it does not look good. Next thing is the tileset you chose its not good for BW styled OWS because of the doors on your tileset, BW ows won't fit in them. I don't know what else to say. If you want any mapping suggestions I can give you some but keep in mind I'm not the best mapper around.
Keep on working and credit proper people for tiles you use.
