This looks like a pretty plain card, but in person it just pops.
The background is done with glossy black card stock. I put dots/swirls of Marvy Metallics on the card stock and then wadded up a piece of plastic wrap and dabbed all over the card stock to spread around the metallic ink. You have to dab the ink quickly as it dries rather quickly.
The angel is by Penny Black and is stamped with pigment ink and embossed and then painted with Pearl-Ex paints.
