I feel a little silly giving a master like you suggestions, but here are a few thoughts I had:
1. Your use of background music is great. It supports and adds interest rather than distracting or overpowering.
2. Some of the exit buttons on the individual projects shut everything down so that I had to go back and find your link to look at more. Even though they say exit, because they were on individual items, I expected that they would have just closed that item and allowed me to continue moving through other items on the menu.
3. The title-type images that include buttons threw me off because I expected the buttons to work, but they didn't (because they were just images). Maybe you could hide those buttons when you get the screenshot/image.
4. I was sad that Carrie and the vet I chose for her didn't work out. :)
