You can explore other artworks from people and click on their name if you like their works. You can check some of their followers and see if you like their work too!
It's hard to search for specific artists unless you know their artwork titles or their username but if you need help with anything else, feel free to ask and I'll see what I can do.
If you want recommendations for people to follow, or if you want to see certain artworks, joining some groups definitely help!
