Took back the sculpted model into shading to see how it worked. Fairly happy with the results. Need to go back to sculpting to get a more fluid pattern then add a glass material that covers this rocky surface. Later on I will also add something glowy inside. I'll hope to paint some textures to control all this as I think manual work is needed to create the details I'm after. You can also hint some spots of saturation, this is my take on a iridescence effect. I'll start introduce some colour here as I'm thinking of making the next phase to look like something the Hubble telescope could have captured.
