What a cute idea! But as a mom... I wouldn't buy because I enjoy reading to my kids. To me... just playing a CD isn't the same. However, it would be could for road trips. We don't have a DVD player in the car and probably never will so a book on CD is great. And, I think some parents would feel differently though - I know some people just aren't comfortable reading aloud (my father-in-law) and this is a great way that children and adults can still share a great story.
Also... Your photos could use some punching up. Some of them are little yellow, like this one:

Don't give up, because it really is a cute idea. Have you tried working the craft fairs? Many that I have been to have booths for books and cds for kids and that might be a great way to get your name out there.
