as you can see the shader looks too metallic for me, I would like it to have more of a cold feel to it, more of an icy blue to it. i did find something good about this shader, i have listed it bellow, this is what i want so i wont need to UV map the cave when it comes to adding texture.
"The shader is 100% procedural which means that it uses only 3d-textures and that
there is no need to consider UV-mapping"

someone else has commented on the fact that it can look more metallic than icy.
the next image shows a shader which has been designed to work with a HDRI map, so in theory having a dark HDRI map will give me a dark ice cave effect.
this is the effect of the shader with a very light HDRI map.

this was the last shader i found today, it wasnt as good as the rest but i think it might do very well if used for a far away shot.

i do like how they have added an object inside the ice. looks cool and it has given me an idea. i will show it later on ;)
