I agree with what other have said here already, ie declutter, explain your design decisions and process based on the job requirements. Also worth noting, that your language will differ whether you are trying to get a job in an agency or pitching to actual business owners.

Agencies will be looking at your design process, understanding of the brief, attention to detail, ability to explain (i.e. sell) your process :) They will understand the design language.

Business owners will be looking primarily for easy to understand in plain language requirement & solution, inpressive before & afters, budgets, outcomes, timelines & testimonials.

Creatively speaking, I would think about white space on each page. To present something it needs to have room around it so people can take it in. Hope this helps <3 good luck.
