I create this character with many influences like Carlos Ortega, Disney, Pixar and a few others, the reason I used the case instead of using a contrabass is because originally she was going to carry it but didn't like how it looked.
I used mostly blender, only used photoshop for the textures and controlling levels after render, used cycles, 2000 passes, it took like 2 hours to render.
Title: Pequeña pelirroja de pelo corto que toca el contrabajo
(In english is little short haired redhead who plays contrabass... without realizing I made the girl of my dreams)
Sorry for my english
