Is this a good internal linking structure for my site?

I’m working on building a site from the ground up, and I want there to be an immediate focus on good internal linking. What do you think?


The arrows donate the direction the links go to.

Note: “Main keywords” would be the home page

Each cornerstone article would be on a specific high traffic keyword

The smaller boxes would be relevant articles that are shorter but each in some way related to their relevant cornerstone topic and only link to that one
