Old world mural

My son and his wife are in the middle of a major remodel on there home. They are adding rooms, redoing their kitchen all new flooring etc. It is a major mess right now. I promised them that I would paint them a mural on the travertine tiles they are using for their backsplash. I have done a sketch that I am happy with and they also like. I will be painting directly onto the tiles in washes so that the beauty of the travertine shows through. I do not want it to have a heavy painted look or resemble a decal stuck onto tile. My goal is for the look to be soft and old looking, almost like it has weathered with age and now is only a hint of a painting. I am happy with mine and I hope they are happy with theirs, the tile layers are waiting for me to paint it so I need to get it done today. I will post it as a WIP or a slide show so you can all see the progression, I will hopefully photograph it up too so we can see the end product all finished. Here is the prelim drawing that was approved. I might make some changes as to spoon placement etc but the composition is there. I am not going to add the "text" on the pot, I was just playing with some ideas. I would love to hide some personal thing in there somewhere, like there name or something special just for them but I don't want it to be too obvious or the next owners will not appreciate it.
