here is my first 2 submisions to your contest.. Both designs are based on the 3 things you want to communicate through your logo.. Design #26 base is the target with E and D. and design #25 based on the power international symbol and E and D.. And if we say that the grey area is the problem the blue is the path of the solution... Clean and straight lines (not flashy or fluffy)- Clean and straight solution ...
LOVE where you are headed! I'm pretty happy with entry #26 (your first), colors and fonts. Could you make the gradation in the emblem look a little like echo waves? Not sure if you could texturize them that way, but would be cool.
Any way to put the ED inside a triangle instead of a circle?
