I have been asked a number of questions this month about being like other "great announcers" or famous voiceover artists. Those people are successful and have great skills and much can be learned from them.
However you do not have to be "like them" but you do have be be as skilled as they are. There are many examples of VO artists who were very different and whose "styles"were joked about and thought incorrect. Lots of those peoples styles then became very popular, HAH!
You must always believe there is a place for you. You must always prepare like there is a place for you. You must always know that your best chance of getting work, is to be yourself.
