[Feedback] Portfolio Page

Hey guys just done with my Portfolio Page project. I wanted a minimalistic and simple design which is easier to navigate. There were certain things I wanted to implement on the navbar but wasn't possible just using css (or just too hard), will be coming back to it after JS. https://codepen.io/chopedada/full/EXpMex/ Can I get feedback/suggestions on the look and feel of the website plus the efficiency in code? I'm always open to writing better code to get similar results. Thank You!
