I love the "milky" feel you have given here! It is more impactful on the dark background #24. The white background may be necessary for future print requirements, web etc; and #23 is great - although the visual impact is not as strong as #24...
What could we do to bring the MLK (Martin Luther King) "I have a dream", inspiring + learning ideas into the logo? Any ideas?
Great logo!
