Choosing work for exhibit submission

I'm so bad at making choices. Please help me! I'm entering an exhibit, here is the prospectus. The theme of the exhibit is play, which my pieces are all about, so I think I have a shot at this one. Please help me decide which three to send in.

the cup:

The blue platter:

The green platter:

The yellow platter:

Or the red platter:

So which three do you think I should enter?
