Coming on nicely!
American avenues generaly run dead straight, but for compositional purposes, wouldn’t it be better for the road to curve off away to the left? You could then have an even lower angle of view, without having to show an infinity of houses.
Swinging the camera around to the left would bring the scaarecrow closer to us and more dominant in the scene. With him crouching, you should still be able to see the witch over the top of the hedge and the fact that only we can see Jack would be clearer.
Have you thought how to light this? I might like to have the scene lit only by the light escaping from the doorway, knifing horizontally across the middle of the stage; with the children lit from the side by this and fill lit by the sweets on the ground. The scarecrow would be lit dramatically from below by his own pile.
Cheers,
