Welcome to Hive. I see you have no HP, which will limit what you can do and so I will delegate some to get you started. As you earn some Hive that you power up you will not need this help, but it may take a while. You can request a temporary delegation from @giftgiver. You need HP or your vote is worth nothing. It is best to just vote on posts to start with and no more than 10 times each day as voting power needs to recharge.
My initial suggestions are to look for people who share your interests. There are a few Ukrainians here and lots of artists. Check out relevant communities and contests. Commenting is a vital tool to connect with people.
I see you are not following anyone, so you need to find interesting people or your feed will be empty.
You should provide some verification of your identity. A photo with you holding a piece of paper with your username or a video is good. If you have other social media then link to your Hive account from there. People like to be sure others are genuine. If you post your art then sign it with your username to make it clear you did it. Some people are picky about copies of existing work, so include links to the sources of your inspiration.
Have fun with Hive and in time it may reward you.
