Help with ideas on how to make a good navbar

Hi everyone!

So I made this, but I still wanted to add a Navbar to put my brand and and navigate through the website. But I feel like I run out of ideas as to where to have it fixed.

I initially had inspiration from Rolls Royce website, but I can’t seem to make it happen the same way. Any suggestions? (:
