I decided to go with Avatar:
I really love my index fingernail and kind of wish I had done the other half of her face on my middle finger, rather than the tree of souls.
I mostly used acrylic paint for this mani, because of the detail. However I used Maybelline Dark Denim as the base colour, Sinful Colors Nirvana for the tree and Revlon Aquamarine as a topcoat on my ring finger, as the white was too bright. I finished it all with a Jess Matte Topcoat.
