Doc to Review

Good job on your work. It's quite a lot, but just skimming through the document, I guess what it needs is better formatting and layout. There are pages where images are too close to texts, or they are just along the border of the page. It makes it look a bit cluttered seeing as how images don't follow margins.

The texts also look too close to each other as well. New lines, or even starting on new pages for new topics would be a good idea specially if it will be for a new section.

That way, it will be easier to look at and won't be too confusing.
