- check your work using basic recommendations here
- check alt attributes, they must be present (find out more and this)
- logo should be a link to the main page of the website
- use alternative font-family in case the main one doesn't work like this
- check the demo page with different screen sizes (including those bigger than 1700px)
- do not use overcomplicated media conditions (try to follow desktop-driven or mobile-driven development)
- uppercase letters for navlist are made with styles, not hardcoded into html (you have usual text with first uppercase letter in html)
- links should be with cursor pointer
- are you sure you've polished your code? :)
