the cloisters museum guide - smartphone app

I am not exactly sure if this kind of entry suits this forum and i apologize in advance if it doesn't.

I'd love to read your feedback on the idea of this iPhone app that I am working on.

The Cloisters is a medieval art museum that is a branch of the Metropolitan Museum of Art, in New York City. I would love to know if you understand the application by what is on this "page" right now, and what you think of it.
I do not have to make it work. The purpose of this project is to show that I am able to design for interactivity.

I have never played with an iPhone, so there might be flaws on the design. If you catch them, please let me know.

Thanks a lot!
