animated self storyboards

Here is my idea for my animation in storyboard format. I wanted something simple as its only a 15-30 second animation. There's not much time for a story really I think my animation is going to be about 20 seconds long at 24 frames per second. 
The idea is that the background is just white but then the girl peers round the edge of something in the middle of the screen. then she runs out and plays then runs towards the camera really cheekily. I'm hoping it will look cute and make people smile and I'm really hoping it moves and looks like a toddler! That's going to be difficult.

And here it is put into an animatic...
