Senior photography is not something that's a big, or even noticeable market in my area, but in general, I think that these images will appeal to a certain segment, but I'm not sure they're mass-market, unless you can inspire a trend, which I suspect would last one or two seasons at most. That said, I think they're very good images, well thought out and creative. What I can see is these appealing as an 'add-on' to a more traditional package.
