I do not understand how section 5 is structured. I would make three separate subsections, i.e. I would number 5.2.1 as 5.2 and 5.2.2 as 5.3. Moreover, for consistency, I would include H1 in the title of Subsection 5.1.
In 5.2.2 the numbers reported are not consistent with Figure 10, please check. Also, the caption refers to Left but I think you mean Right.
