SLOWLY pour the vodka in, if you can pour it onto the side of the glass instead of directly on top of the juice, you should be able to get the layering affect
Add pomegranate seeds for garnish
Cheers!
Notes
If you would like to sugar coat your martini glass rim, rub the lime slice around the rim, pour red (or green of gold!!) sugar on a small plate, place the glass upside down on the plate and twist it lightly to coat the rim, then make your martini.
