This one is really nice and clean, and simple.
I also wanted another excuse to draw scales. So these remind me of mermaid tails with the pastel shades sponged randomly onto the accent nails. I like the cute scalloped french tips on the other nails too. It's a very clean, and simple looking manicure.
I sponged "Pastel Teal", and "Pastel Blue" (by Kleancolor) and "Lacey Lilac" (Sally Hansen) onto the ring finger, and went over top of it with "Age of Aquarius" (Color Club) for the scales. The base I used was "French White Creme" by Wet n' Wild. This one was really cute and easy to do.
