What a lot of your work has gone into this quilt. I have never made an art quilt. I have done pen and ink. I think that maybe the use of a speckled fabric for the house would suggest a stone exterior rather than the blocks. Also maybe a light rust stripe to mimic the tiled roof. I would skip the flower vase and instead use flowers topping the stone wall. What a big mouth I have. What ever you choose I think it will be great.
