Hi - thank you for your observations - they agree with my feelings about the final thing. I think the scene where I failed in particular was the squirrel encounter. I thought I would place the squirrel closer to the camera, but then I found out I have to place it further into the scene in order to avoid collisions with the moving camera on the track and also to make it possible to see the whole creature (seeing only the face or a portion of the body did not work) till it ended up on the same plane with the kids. At the same time I also wanted it make it look like that the audience notices the squirrel either prior to the kids or at least not later than kids (so that it looks like the audience is noticing the kids through the observations by the forest animal). Either way, now I know I cannot have the off-scale features (in this case the kids and the squirrel) on the same plane - it does not work, as you pointed out. Now I think it really looks like the squirrel must be some giant - or we can just say it is an enchanted forest with magical creatures and it is all right .
