Default sans-serif font family and default link colours are not what you would expect from anyone claiming to be a web designer. Your website is your chance to show off your talents, and it’s a potential client’s first impression of you. You should make it as good as you can.
Change font family, and the link colour (you can use the teal in the logo).
It does seem very simple and user-friendly though, so that’s good. I had to run it through Google Translate in order to understand anything, but once I had I liked how simply yet also effectively your work is shown.
