Entry #3: Not even close. The most important part of the logo are the words The Moto Channel, and here they are so small you can't even see them. Also: Please no Web 2.0. We don't like the look of Web 2.0. Also: We specifically noted that the Logo should be a ratio of approximately 4 to 1 width to height. This is not even close, this is basically square.
Entry #2: We don't like the play symbol in the first O of Moto. Please no references to video or television (especially YouTube) or Web 2.0 or video players.
Entry #1: Way too much black. Remember this logo will never be in black and white. Maybe you shouldn't use any black at all. Certainly you should use less black. And refer to comments of Entry #2 and #3 that are applicable.
