I wasn't going for a literal pumpkin, but these colors and this design concept is "pumpkinesque" to me. Orange and green speak Halloween manicure to me, so here you go!
I painted three coats of China Glaze Breakin' leaving space by the cuticle. I added Dots Nail Glitter Flakes in orange from Esther's Nail Center and filled in the gaps with LA Splash Cosmetics in Immature. At the cuticle, I painted two coats of China Glaze Liquid Leather. Over the entire manicure I painted one coat of Seche Vite.
