I really like the color combination, but I think I should've done the lightest color first and finished with dark. The darkest green is Kleancolor Green Grass, the middle is Sinful Colors Happy Ending and the lightest is Orly Green Apple. It was all freehand with the bottle brushes. I'm a fan of any nail art that doesn't require any additional tools.
What do you think of this? It's a bit odd looking, but still eye catching and fun.
