Well, it certainly is a nice texture - in fact, I like all the textures you have
used. Especially the egg at the top-left of the image - I think you got that one
just right!

Some people mentioned problems with the wood texture. I believe the texture is
fine, but this image gives me the distinct impression that you have turned on
radiosity at the last minute - without setting the ambient component of the
texures' finish to 0.

That would also explain why the grout looks a bit red close to the edges of the
tiles - it looks like they are actually emitting a small amount of light.

If you switch between using radiosity and not using it, declare a variable at
the top of your scene (e.g. #declare use_rad = 1;) and then inside each of your
textures turn off the ambient if you are using radiosity:
finish {
  ...
  #if (use_rad) ambient 0 #else ambient 0.3 /* whatever it was */ #end
}

You can even turn it off by default, with:
#if (use_rad)
#default { finish { ambient 0 } }
#end

....but note that if you do specify an ambient value in a texture it will
override the default.
