Profile card using HTML & CSS, Responsive

This is the first time I have built something myself without following tutorials, I am aware it is not a very big or complex task but I am glad that I completed it. I believe there is a lot of room for improvement and any advice on how to make this better would be great. I have managed to make it responsive for phone, but need to learn more about media queries. This project is also the first time I have used GitHub and I will continue learning the best way to use this.
