This mani was done for a friend who specifically requested it, inspired by a custom-painted keytar played by the keyboardist of our favorite band. First the inspiration:
Henrik Klingenberg from Sonata Arctica with his epic green keytar
Now the nails!
I used L.A. Colors - Palm Tree for the base, and used tape to mark off the pieces on all but my thumb, painted over with Wet & Wild Wild Shine - Metallica. On the thumb I tried to re-create the gradient on the actual keys with the sponging method and the same colors.
