Porfolio Page's done, any feedback is welcomed

Hello everyone. I just finished my portfolio page and i’d like to get some reviews.

Here’s the link:

There are some things i’d like to know.

  1. How does it look aesthetically?How can it be improved to be more easy-in-the-eye?
  2. Functionally, is it good? Responsive enough?
  3. How messy is my code?
  4. PLEASE take a look at the social media buttons and tell me how and if i messed it up at all. The hover thing.
  5. My burger menu doesn’t work and i can’t figure why. Any ideas?

Thank you in advance.
