Hi!
Wonderful logo designs... thank you for your submissions!
Some suggestions:
1. Please invert the black and white, so we can see it on white first.
2. Please make the "E" and "C" rounded (like:
#1 or #18).
3. Please make the "EC" thinner, finer, more sophisticated.
4. Please try the "E" with a diamond design.
5. Please add some detail to the stem in the "E", if possible (like: #18, but better than that).
Keep up the good work! And, thank you again!
