Hi Amin,
In the solution, the social media icons are slightly different then they are in the design.
Also in the design there is a circle around the social media icons.
You can find similar icons on FontAwesome & add a circle around it to match the design.
All the best.
There are a few things that you can do in future projects.
In a starter code there is README-template file, where in you can put in details like screenshots of your project, links to your solution URL and live site URL, approached you used to complete the project, What you learned etc.
You can then delete the readme file and rename README-template file to readme.
It's always a good practice to have a good Readme file, especially for more complex projects.
