Serene showed me a picture and I replicated the design for her! The result:
The leopard prints were done on Gelish Twinkle as a base, with Artistic Colour Gloss Java Java for the spots, and a mix of Angel Pro Gelly Polish in #29 mixed with #30 for the outline of the spots.
The gradient was done with Gelish Desert Sands as a base, then Angel Pro Gelly Polish in #39 for the tips, with Gelish Water Field to soften the gradient. 🙂
