@haikushack How many seconds is it? I have a friend who used to work in broadcasting and she's concerned my 60 second one is too long.
I use music, images, and text. No voiceovers. I've been trying to cut down to 30-40 seconds.
I have two - one for "available now" and one for "coming soon." I want to release coming soon in the next week or so. They will focus on different aspects of the same book since I've discovered it appeals to two different markets.
