I love how dynamic the image is already!
What you've written sounds a lot like what I've been struggling through with my own 'flight' illustration. But at least you've got a sketch!

There's a sticky-note in front of my desk that I find helpful, which says, "how do you want the audience to feel?"
It might help to write out some notes about the reaction you want, the personalities of the children, their backstory, or even just what you'd really like to draw. (I don't guarantee this will help, but it's worth a shot.)

I'll throw out some random ideas if you like:
Could someone or something be riding on the aeroplane (or clinging on behind)?
Could the children be 'trapped' - maybe between the railway and tall buildings, or in a tiny back yard? So the aeroplane can do what they can't: fly away/escape.
Maybe there's a 'baddie' in the image... Are they Hansel & Gretel type characters?
Maybe the plane could be really badly-made and misshapen, yet is flying way better than the boy expected (his could be lying somewhere)?

I hope something here helps!
