Dalai - Character Design

I took a part in a small challenge. Its aim was to design the character based on 3 keyword: lighthouse, shrimp and guitar. The other requirement was to use only the colours from the chosen colour palette. My character, named Dalai, is humanoid creature living in the ocean. Her skin is covered with shrimp's carapace. When dusk falls, she enjoys playing the guitar at the coast in the light of nearby's lighthouse. She wears modified, conductor-alike costume.
*I used shrimp's anatomy as a reference.
