Hello @liza.bakulina, welcome to Steemit! This is a good introduceyourself post and those are some great pictures that you've shared.
I'm pretty new here myself and a learning more and more about the platform every day. It's really cool to follow and interact with such a diverse group of people from all over the world. I'd like to share with you a couple of posts by experienced users that you might find useful.
This post by @allasyummyfood has 14 different "how to" videos for new users. She put a lot of time and effort into it and I've used it as a reference plenty of times https://steemit.com/steemit/@allasyummyfood/steemit-lessons-all-parts-in-one-post-for-beginners
Another good read for new users is this post by @dragosroua about steemit etiquette which I've found very informative. Reading it will help you avoid making some mistakes that many new people make in their first days here. https://steemit.com/steem/@dragosroua/steemit-newbie-faq-netiquette-how-to-avoid-being-a-steem-douche
Best of luck to you in your Steemit journey!
Thank you very much, be sure to read everything !!)
