Vintage Love moo's

These are my " vintage love " moo's for this weeks challenge, I stamped a collage onto thin white card, cut out the hearts, added the photos behind and then placed onto heavier cardstock, I used 3 shades of pearl ex powders to colour the collage and the printed words, sealed with spray sealer and edged in black, not sure why but the pearl ex colours have come out a lot darker in the photo ????
