What I see of the story is that two children are playing on a seesaw in the snow, and apparently they have had an argument, the girl has ripped up the teddy bear, and she's walking off. I guess my question would be, Why are they in the snow? Why is there a seesaw in the middle of the woods (or is it a backyard)? How long have a they been there for there not to be any other footprints than those of the girl walking away?
In the case of Lee's image, I get that the treehouse looks well-lit and welcoming for the guest who is arriving (2 sets of tracks), and in Jon Klassen's, it's obviously a solitary nature scene with a fox and no humans at all. Your scene is unusual enough to make me curious as to what happened, but I need some more storytelling clues help me understand what's going on. My first thought is maybe to add a house in the background that the seesaw belongs to, but that's by no means the only option.
The image itself is really lovely and I don't think there's a problem with borrowing ideas or techniques to put them together in a new way!
