Hello Akerman
My favorites from you are
#63 and #64.
These are strong and bold - really stand out! But - I think they might be a little to masculine overall.
Your other designs are attractive - but a bit to clinical looking. The AA does not have any symbolism other than the two first letters in the name. Would prefer to see something eternal - the olympic flame for example - or something symbolic of movement.
Thank You!
