About the #44 and #46, you right it has and edgy look. But I also shaped the E typo to look like an old style of microphone that symbolize entertainment or live show performance of an artist.
#45 and #47 concept is an artistic and elegant signature.
I'm sorry I have to withdrew some of my entries, considering there are similarities one to another (just a tweak change of the color combination). And I'm sorry to see that my entries still far from your expectation (as seen on the ranked place).
Perhaps you have some opinion what to change on my concept? I'll be glad to rework on it. Thanks.
