Leopard print nails are really simple to do. All you do is paint a base colour and leave to dry, then paint dots of another colour and leave to dry. Then using a black nail art pen, do two curved lines around each dot, then when it's dry, paint a clear top coat.
It is surprisingly easy to do, and you'd be surprised at what colours go well together. I had a fair few amount of oversized false nails, and decided to experiment.
