NOTD- petrol/gradient effect in black and green TUTORIAL

Hi everyone,
Today I want to share my latest nail art creation.
I have seen many gradient manicures lately and I decided to try something similar. 
I think that the final effect looks like petrol :) It is quite easy if you follow this steps:

1.Apply a generous drop of black polish to the bottom of your nail.
2.Quickly apply a drop of green polish to the top of your nail.
3.Blend two colors together with a tooth pick or a needle/pin. Repeat on each nail separately.
4.Wait for the nail polish to dry and apply a top coat.
5.Apply a tiny drop of green metallic polish on the tip of each nail and dab it on with your fingers or makeup sponge. 
Does it sound easy? Let me know if you decide to try this, I would love to see your results :)
