Feedback on beginners portfolio

Live demo: www.jackmitchellsportfolio.com

Git: https://github.com/Mitchell2398/Portfolio_Website

Any constructive feedback is greatly appreciated, this was my first big project and I know there are an unlimited amount of things I could improve on so please let me know. Things to note:

• website is hosted with gh pages and a custom domain, currently having problems with this working properly

• projects are all dummy and I know need to start building my portfolio (any project recommendations appreciated)

• website is meant to be responsive but anyways I could improve my css would be great :)

Thank you to everyone who takes a look!
