Once your gradient has dried. We will do create the nail art. Starting with the index nail, take a thin detail brush with blue paint on it and on the left side of the nail make a long line and then two lines at the bottom of that large line and then two smaller lines at the top. For the next coral, take that same detail brush with a light green on it and make a long line on the left side of the nail then a short line near the top. Next to that make a shorter line with a small line at the top.
The middle finger is similar to the index nail. Take your detail brush with with red on it, make a curved line on the sand and have four lines coming from that, then make a few small lines from that. Then just like the index nail make a the same green coral in the middle of the nail. Also on the red coal you make some small yellow dots on it.
Lastly on the ring finger we will make a star fish. Make a large star shape with brown paint, then once that is dry add some peach dots on the points of the star fish.
