IMO you should work on the form of the fluid, better defined flow, generating more details to get the epic feeling. Different fluids behave differently... water is not dispersed as blood or quicksilver, chocolate, crude oil... so when you get the form right, you'll know what material is made of. For now it feels more like a semi fluid jelly, a marmalade... no matter which material you put on.
Either study the form more or go for the material that your idea/conception started with.
