Update digital brochure and installation guide

I have a digital brochure that includes an installation guide for a building material. I need it updated and a section to be added where we have updated the product so corners can be folded. Therefore I need a new image keeping in the style of the existing brochure to demonstrate how to fold a corner and a new section covering this.

The install guide can be found here

We have some basic sketches that show how the material can be folded that we need to be stylised to sit in the brochure. With amendments this should be around a days work
