As an author pursuing publication, have you thought about the fact that you're going to need a professional headshot? Many people brush off the idea initially, thinking they can have a friend take some nice shots in the backyard. That might be true and you may think your snapshot looks great, but many people will perceive it as a snapshot or an amateur photo. You don't want the look of an amateur - you're a professional all the way. A great headshot is key to presenting exactly the right image to the world - whatever you want that image to be.
