You're layouts are looking top-notch Claudia, the only thing I would suggest is starting the mobile layout sooner, at 700px. This will implement a mobile layout that will work well for a tablet device with responsive design in mind, and stop the elements from collapsing at a lesser viewport width.
The navigation can use larger buttons or just a border would work as well, I like how much effort into making the button element, and want to see that kind of consistency 👍
