Would love to see a clear screen shot or two of your material. I am trying to recreate the shader now and a few of the nodes are hard to read. Assuming by the lack of other folks bragging they got a similar look I may not be alone. If you could include a zip of the material would be even better!
I have found something put together already:
He included a zip of his material: http://www.mediafire.com/file/djaua9wy8emjry6/May.zip
Looking at May’s material, it is much more complicated with twice as many nodes as yours and I still find I like the look of yours better. Might be worth looking at though for anyone interested.
