One thing that's been doing my head in for a while now, and unnecessarily annoying as it's such a simple fix... is the material mixer and the texture mixer nodes, the mixer percentages are reversed and I can never remember which is which;
Texture Mixer
http://www.mediafire.com/view/8x1yf494o ... ix_tex.jpg
Upper input is 0%, Lower input is 100%
Material Mixer
http://www.mediafire.com/view/vxg3n1bk3 ... ix_mat.jpg
Upper input is 100%, Lower input is 0%
If I had to choose, I'd make them both so the the lower input is 100%, as this is the second input and the percentage which will be mixed with the first input.
Longstanding minor niggle, easy fix..

I forgot the lesser used cosine mixer, which like his brother the texture mixer is also o% upper input and 100% lower input. So poor old Material Mixer is a bit muddled and should really fall in line with the others
