I'm happy you finally got your site up :) congratulations!. I also think something could be done to your diffuse and spec it would help alot, but I'm having a hard time thinking of how to explain it, I'll come back with something good to say hehe.
1- Diffuse is way too cloudy. Tone down the contrast in the noisy pattern and add more real surface detail. 2-spec is a decent start, but nowhere near complete. Darken what you have down just a bit -- maybe 10-20 %, and start working scractches, edges, and bright details ontop of it twice as bright.
