Thought I'd post a bit of an update. I should also mention that this is based on a 3dbuzz tutorial, credit where it's due, though I've changed the mesh significantly and added some detail and the materials.

Got some better success by altering the spec, and increasing the reflectivity and adding heavy blur to it. Still to add the fresnel. Cheers for the input gster.

edit: I forgot to ask gster or anyone else checking the thread... on which channel of specularity is the fresnel best applied, eccentricity, roll of or colour?
