ah yeah to be honest I did wonder if the pages were compressed for financial reasons XD
that being the case you did as good as possible, and especially working with a raw script that's a lot of figuring out what panels show what content, and constructing the flow of the comic all by yourself.
deciding on panel and page content varies massively depending on both the genre of the story and your own artistic style, as some artists focus on very small details/actions, which adds more realism but takes more time to tell a story, whereas others focus more on facial expressions/emotions etc. So there's a lot of layout variation for even the same story.
My personal advice although not fully tested, is that each panel should have impact in that it is the most of something compared to the other panels. So if a character is sad, you make them really sad, if they are jumping, you stretch their body so they are jumping with all their might. It makes emotions and actions pop more than just drawing things "normally", even if it's technically accurate.
I've been meaning to get more photo real life study done as well, but just fitting it in with all the other art is always difficult XD
