I've added Champagne Mist shimmer paint directly with a sponge dauber to make it sparkly in real life, the catalogue suggests using an Aquapinter brush. Here's mine up close & all "shimmery".
Stamps: Swallowtail, Loving Thoughts
Paper: Summer Starfruit, Island Indigo
Other: Pool Party embossing powder, heat tool, Champagne Mist shimmer paint, sponge dauber
