Regarding #21 My favorite by far. Can you change the woman to a an image like this: http://db.tt/1KxXyxt2. Maybe add some color to the belt since the silhouette will be black. Maybe one option with the sold sign and one option a house.
Hi, here's the updated version of 21: #55 with a better defined waist.
I cannot make the exact silhouette from the picture you provided since it's another designer's, but here are some options with a similar approach: #56 #57
