yes, darker background looks great, but it's a bit unrealistic (maybe apart for a website), since the logo will be mostly used with a white background (stationary, business cards, painted on building, etc.)
the 's' looks a bit weird (almost italic). Is that due to the font? And would it be possible to give the letters more of a 3d effect i.e. like entry #7?
We're still not sure about the blue dots in the face. Somehow it reminds me of measles. :-)
Thanks,
