Hi Grafisimo, you are clearly a unique artist and designer, and thanks for the unique logos. Any possibility of looking at another angle. I have been looking on the web and quite like the idea of a Coat of Arms type logo. The Coat of Arms / Emblem I had in mind, was very much like the old "Royalty" or "Kings" emblems. Where you have the emblem in the middle, flanked by say two eagles (they use to use Lions alot that stand up against the emblem) or an Eagle on top of the emblem (like the American symbol). Then inside the Coat of Arms we can have the four symbols that represent us. Our scared symbol we uploaded, an african symbol (maybe even a african map), a sumbol of light (wings or an airplane) and the 4th one can be the letters SH inter-twined. Also a like the option of a crown somethere providing the feeling of royalty to the logo. Also it must NEVER be an "Angry" eagle but rather a very regal and royal looking eagle/hawk. Some examples are: On istockphoto.com you will find file #File #: 6347108, or go to
