A cute picture, but, ultimately, flawed. Too much whitespace if you're trying to convey a sense of 'they have a lot of these' and too little whitespace to give any other context.
The poses are rigid and not comfortable looking as though they were asked to stand at attention. Not fond of the way they hold the animals they're holding, and your daughter on the right, did she just get out of the bath? They also look like they're looking off camera right just enough so that it doesn't look like an intentional direction, but rather that the image just missed capturing them looking at the camera.
Some harsh shadows (animal next to your daughter on the left's face).
Minor nit -- the string visible in front of the blue bag/box thing.
It's a good scrapbook/photo album shot and your daughters are adorable.
