Paint your nails with the gold until they are opaque.

Next, get your brown (you can use acrylic paint in lieu of polish if necessary) and your dotting tool. Drop some color on a piece of paper so it's easier to dip your tool into.

Make random dots of different sizes on all of your nails like so. These have a little bit of a dark outline because I started with a brown that was way too dark! Make sure you brown isn't so dark you can't tell it apart from your black!

After you have dotted all of the brown, go in with your black (paint or polish) and outline around the dots haphazardly, in C shapes, in parentheses shapes and make some extra little spots in there too where you might have some bald spaces of gold background showing through.

Lookin' good. Now you have this and you will need to clean up any bits of paint/polish around your cuticles. Take a concealer brush or paintbrush, dip it in acetone and wipe around the edges of your nail to remove the excess polish. This is my go to method for clean up, q-tips are good too but sometimes they leave cotton fibers behind.

You're all done! Wait until it is COMPLETELY dry and add your top coat. Add it on thick so it covers up the spots and lays flat, also laying it on thick will help to avoid any streaking of your art.
