Hi,
Ha - isn't that the way, always too much to do.
I've given the three I saw the most to comment on a quick mark-up, it's brief but I hope it's some use. Yellow are note about lighting, green lines are horizons etc, and cyan lines are notes about perspective.
I think you're probably aware of the general stuff about the eyeline/natural-horizon and the drawn horizon. Certainly for the first two from the eyeline the view is about 3m off the ground, rather than a natural perspective.
For the second image I've just marked out the boarders of the light and shadow from the visible light sources.
If you have any questions, please let me know.
