Hi Vadim,
Congratulations on finishing yet another nice project and again on a very rapid learning pace! 
Some ideas from my side for your consideration:
- It’s better to have a more wordy introduction, giving the background context of the problem, as well as more wordy markdown explanations describing the steps to do and the intermediate results afterwards.
- You should use or only bullet, or only numbered style for the same markdown list (like the one in the conclusion).
- The picture after the code cell [2] is not displayed for some reason. Probably this short post can help to resolve it.
- You might consider limiting the output of the code cell [6], otherwise it looks too long.
- Another thing to consider is rounding the outputs of some code cells ([3], [4], [5], etc.), to avoid unnecessary decimal points.
- As for the SQL code style and improving its readability, this guide could be of use, especially the part about white spaces (“rivers”).
- Be careful of typos, especially in the subheadings.
Hope my suggestions were helpful. Good luck with your future guided projects and keep this fast learning!
