LOVED playing with this!
Added a texture and loved the effect but then couldn't see the glass effect! So I duplicated the photo and added it in overlay mode above the texture. Then I went back and added glass blocks to just the background of the bottom photo...LOVE the added depth that gives to it, esp. around her chin!! I used frosted on all of the 2 photos initially btw.
