Entry #6 is best out of the 4, in my opinion, as it exudes a certain personalization which is what represents me. I'm only concerned that the letters wouldn't be as legible if the graphic was minimized to thumbnail size, and the font may be a little common. I'd also prefer if the word "entertainment" was slightly darker. Another idea would be to make a microphone wire exiting the mic and creating an underline (freehand) seperating my name and the word "entertainment". GOOD JOB THUS FAR!
