FCC Portfolio Feedback

I just wanted to post my FCC portfolio in here to get some extra eyes on it. Any feedback would be greatly appreciated. I still plan on adding a sticky nav, smooth scrolling and a real bio of myself. Currently it’s just some space themed placeholder. Thanks everyone.

Looks good man! Nice, clean and simple layout.
One thing I did notice is that your navbar loses some of its items on smaller mobile views, looks like they stack below and thus drop out of the viewable area.
