No, it's still a bit Pete Tong
I stamped over it using Konad plate m63 with Maybelline Forever Strong - Lilac Pearl, which is a damn good stamping polish and it's 99p on eBay. But it just wasn't right. The photo is awful, the Avon Matte kept chipping so I had to repair the stamped bits by hand using an old liquid eyeliner applicator and I just wasn't sure about it. Nor was the Avon Matte, as it kept chipping away until I got the right hump with it and went over it all with two coats of Saffron Colour 06 (black with silver glitter, about a quid for a bottle).
Saffron Colour 06 Saves The Day
You can still see the Konading beneath the glittery layer because of the flash and because I missed bits out on the sides, but it looks fine in normal light, like a shiny shiny starfield. Nice.
