This suggestion is not directly related to your actual code, however, I wanted to remember you that you need to update the README file for this project, when I submitted mine that was the only problem that I had, the README was empty
Branches
I see you have multiple branches in your repo, however, it would be great if you had less of those and just concentrate in only one "feature" branch, this is because it is kinda difficult sometimes to find the latest version of your code when you have all these branches.
Overall conclusion
I really like the way your code is looking so far, hopefully, you can continue doing the same good code
