The Princess and the...?

With David Finch's examples, between panels 1 and 5, we see the two characters flipping from left to right. In the previous lesson he introduced us to the 180 rule and also warned about flipping the camera angle. In his example it didn't look off and ran smoothly from panel 4 to 5 (to me anyway). So, my questions are... 1. Does the 180 rule apply from panel to panel, rather than taking the whole page into account? E.g. you could keep moving the camera angle around by 180 from each panel to the next, and within a single page having the camera angle move a whole 360 (or more) around the characters/ scene? 2. Can you break the 180 rule by using the character's POV to lead you to a new camera angle?

I have a question about figures intersecting the sides of panels. David's description makes sense, but I've also seen super close-ups that essentially cut off one half of the character's face using the top and side of the panel. Things like that. What's an effective way to do this without it looking odd in the way the video describes?

Here's a comic book page I made a while back before ever watching these lessons. At the time, I thought I was being clever using a tangent between the lower jaw in the smaller panel and the side of the horn/petal/nose thing in the larger one. I wanted to ask two questions. 1. Do you think the tangent worked in this instance or not? 2. Are there examples of where tangents can be used to bolster the impact of the page or should it always be avoided?
