Well I think it looks just fine! And I asked mr surf girl to take a look, and he does too - so I'm not just being nice. Your pictures with arrows had me completely cracking up, though. Awesome.
Re the speckles, I'm not entirely sure why I got them and you didn't, but it may be because I ground the root at home (coffee grinder) rather than buying the powder. Having said that, some of the powdered turmeric etc that I use will leave some speckles as well. It must depend on the fineness of the grind no matter who is grinding it... I was not actually going for speckles, but they grew on me.
I use the pantyhose-over-little-dish technique for sprinkling cocoa powder as well. I didn't get any smears on the Pretty in Pink soap (for which I used an extremely fancy milk carton mold), but I did get a tiny bit of smearing in the most recent soap I made (wooden mold with freezer paper lining). I'm not sure I care, but I might shave it off.
And re white - my soap was olive pomace + coconut. Very white.
