Modding

I decided to create a creature for NCF and will make a video about manipulating shaders, materials, and textures in the game.
I found the idea of combining ice with fire interesting and decided to try it out on this Fire (Ice) demon.
Where the ice crystals grow, I will create a cold mist, like steam from nitrogen, that's approximately how I envision it. I plan to apply a shader to the entire body, similar to the one used for the water elemental.
Maybe someone can suggest something good? I'm interested in your opinions.
