Nice work, indeed. I like how you developed from an initial idea to the final design. However, you should work on your presentation and post format.

Know the project

I can see that you copied the description from the GitHub. As we can all agree that using an official description is the easiest we can do, it also quite hide whether you actually understand what the project is about.

Since you used one of your previous posts as the starting point, you forgot to update the name to the current project. Pay attention to details. You should enjoy writing the posts and sharing your work instead of taking it as a routine where you produce the same post every time.

Share more about your work

You could include more information on the colour scheme, the number of variations, your work with the project owner and the design iterations. Don't force the readers to click on each and every link.

Also, don't aim the post only for Utopian moderators. That should not be the purpose of your submissions. You should be willing to share your work even without the Utopian vote.

Improve post format

It is obvious that you use your "post template" with changes in some sections. The flow of the content is always the same, using the same structure elements at the same place.

Consider making your post unique among your own submissions. Each project is different and you can make each of your posts different too.

Consider using more appropriate markdown styling. You use headings wrapped in the links. If you want to use headings, you should write some words to it, otherwise, you could use something like bold text, a table or something else to organize your links.

Avoid using small images. Although merging the images for the "proof of authorship" may be better than submitting them separately, it is difficult to actually see anything in there. Perhaps you could either crop only the important parts of the images or include them in a separate folder if you want to include them.

Check Mastering Markdown.

Watch your typos

Always reread your text. There are several typo errors which worsen the reading experience. You can use for example Grammarly to check for typos for you.

Keep up the good work, I really enjoyed going through the GitHub issue and seeing the progress. But as I said, aim your posts to the real readers, other designers and the community in general. Don't make it only for the Utopian moderators.
