Shader looks great, tho the normal on the top seems almost invisible. I really like this tho, I think I can use something similar for a jade statue. But I do think on top of this having a few pieces of geo inside your ice to create the look of cracks that light up at the right viewing angle would be a great touch. 1 last thing and this is more nit picky then anything id say the layer of cracks that seems to be a copy of the top layer beneath maybe just for that layer use your fernsel inverted as a opacity to make them disappear towards the edge of your geo. as for the geo cracks im talking like this, however this is a crystal rock mind you I think youll get my point https://www.google.com/imgres?imgurl=http%3A%2F%2Fspiritwalkministry.com%2Fyahoo_site_admin2%2Fassets%2Fimages%2Fcs_2.219164821_std.jpg&imgrefurl=http%3A%2F%2Fspiritwalkministry.com%2Fcrystals_and_stones&docid=lk6sDMKahaB8eM&tbnid=NXOT-rV4vumsGM%3A&vet=1&w=224&h=224&bih=642&biw=1280&ved=0ahUKEwiLkfK-96TcAhWRJXwKHSErBXEQMwh1KA4wDg&iact=c&ictx=1
