Create custom graphics for my business portfolio blog

I need a designer to create graphics for the blog articles on my portfolio site - https://kendallwmiller.com/blog/ . Ultimately I want graphics for 6 articles with each article getting:
1. A header graphic in an isometric style I can place at the top of the article and also use to post the article on social media (16:9 aspect ratio) that will draw in folks to read the article.
2. An explainer graphic within the article to illustrate a key point and break up the text.

I have attached an example of each to this project.

I will provide a design brief for each graphic in text and want you to create the final examples. I expect to have a few revisions per graphic.
