Coming back to work on this model now. I made some improvements throughout the sculpt. Anatomy in particular feels a bit more solid.
I was pretty fortunate that Supergiant Games recently put out an email that had a new drawing of Celeste in it. Super helpful in getting some of the details that I was unclear on looking right. The mandolin head stock and pegs have been changed up, along with the neck and arm accessories. The skirt section is where I've gone on a big tangent, as I wanted to get the same layered effect without losing the form of the character's legs in a full billowing skirt. A few more details and we should be ready to move forward.
