Social Profile Links using HTML and CSS

What are you most proud of, and what would you do differently next time?

Felt pretty comfortable moving around the elements with flexbox on this challenge as opposed to my earlier ones.

What specific areas of your project would you like help with?

Mostly things to do with HTML.

• Am I doing too much when structuring my HTML?
• Should the links have been nested in a 'li' element?
• Am I on the right track with html semantics?

Thank you very much.
