They're weeping angels, from doctor who... and they're dancing XD
The story's great, I love the personification of the wishes and the "If you touch it you have to grant it" thing. There was one tiny mistake in the tu section:
The room is lighted (lit) so everything sparkles and shines in a fantastic, beautiful way, but it isn't too overpowering.
And another in the granted wishes section:
Out of them steps the happy little girls that met you when you got off your train, but she looks maturer more mature and almost happier.
Overall it's brilliant though :D
