Hi Unwireme,
Well done! I've checked the HTML and glad that you have used the semantic tags like main, section, h1. That's a good confirmation that you really care about the HTML structure.
According to your question, the circles are a bit tricky in this challenge. I have used pseudo-elements, position absolute, vw and vh, background url, transform translate and @media (in your solution they are not very stable on different devices). Also, I'd recommend learning more about the alt text inside of the alt attribute - for example, you can just simply type the name without "photo", because the tag img indicates that this is a picture.
That's it from me. Ps. Don't forget to upvote any comments on here that you find helpful.
Greetings :D
