Paint a light green nail polish in both sides of your nails just a half of your nails.
Next paint a circular shape or just to connect the line in both side of your nail just leave a little space on the top for its eyes.
Make a white dot on the space you made, second make a black dot on the white dot to make an eyes.
Next make a small red dot to form its cheek
Lastly make a small letter "v" to form its mouth
Apply your top coat to finish:)
