You have high quality images and good design, but I don’t like the footer.
You have poor typography on the footer.
The footer does not have enough quality like other sides.
The content is more complex, try to reduce it.
The social icons are not high quality.
Off course you have a good start, but your nav menu is need polis. And also low level headings font family.
More space is not good in between content and sidebar.
It would be better a transition effect on hover for portfolio items.
