Well,
You sad that the photos weren't edited, but its not true. For example at the cemetary its clear that the drawing around the ghost was not made in flash.
Improving ideas:
-------------------
And I think you should show the photos first wo any help and then draw around it with comment to let people think what to see on the picture.
Also you should use higher sound quality, sometimes it was annoying and loud. Try to edit sounds with a professional sound editor, like SoundForge (my favourite).
By the way sure it's a good work. Not a good flash, but a good collection.
