#7 is a good concept, just needs to look a bit more sophisticated/clean
Not sure about the colors on #8
#6 looks good but the font for APTA needs to be a bit cleaner and more professional. The colors of the continent can't be too colorful. This looks a bit too gay-pride.
I was aiming to have more corporate and clean logo, 80% corporate and 20% illustrative. I wanted the "APTA" to be the primary visual, strong and to-the-point, while having Africa a smaller icon but powerful enough, through the colour choice and positioning with the typography, be a strong visual representative.
