Perhaps your explanation makes sense to those familiar with the jargon, but otherwise it leaves much to be desired. For example, 'gluing' edges or faces together is difficult enough to visualize without being more specific; and how does fig. 11 represent a 'double torus' formed by gluing opposite sides of an octagonal cell together? Please. You're going to need to be more descriptive.
