Feedback for my portfolio (+ extra tribute page)

Hey, I’m looking for a review of my portfolio here:
PORTFOLIO

Overall, I’m quite happy with how it turned out especially how I saw my improvement in my portfolio compared to my tribute page (which sucks really). Although, I guess it’s because of the bunch of research that I have to do for the nav bar and other aesthetic stuff that I adore.

Problems that I see though is that my navbar is being funky when I reach in the ‘contacts’ section and I really don’t know how to fix it… Then added to that is my code is really messy… Like really messy so I apologize for that (;;-___-)

My pathetic excuse of a tribute page:
Amelia Earhart

P.S.: I am officially in love with the parallax scrolling effect. Thank god, I read a bunch of stuff on the internet.

THANK YOU IN ADVANCE BTW.
