Here is my first entry for a SVS contest. Enjoy, greetings from Berlin, Niels
The problem I see a bit is that the whale is sort of too still. Lets assume the kids were having a picknick on what they thought was a nice stone and suddenly it starts moving and they fall over.
That movement is not shown in the picture. Instead the whale looks like the moment just before he starts moving, but the kids indicate some sort of rapid movement already.
Although you first sketch was a bit confusing, at least the whale looked like taking off with some energy.
Plus the whale looks like being out of the water. Is the whale important? Maybe a giant turtle will do the job better?
The first thing that comes into my mind is, that "Being in the center of the storm" could be a bit too obvious for the subject, as probably a lot of people will pick something similar. Someone in the middle of chaos not realizing it.
But if you want to go for it I would choose a more dynamic approach, different camera position, different view point. More going on in the foreground as well. In general more chaos.
