The first thing I notice is the theme. If I can imagine myself scrapping with it, then I'm likely to choose it. Then the colors. Though it's easy to change the color in Photoshop, so that's not disqualifying if there's an element I want but don't like the color. And I agree, uniqueness attracts me too! I've been collecting digiscrap stuff for over a decade so I don't really need anything anymore. But sometimes I find new things that inspire me.
