Portfolio prototype done (using pages). Feedback needed

This is the 1st time I “design” a webpage. Not gonna lie, panicked a lot.
I have no idea how to do design and haven’t done any sort of design work in my life…
Here is the prototype I made. Using pages. I will try to upload the screenshot of it as well as the source file. *If you are using mac you can open it. *

Any suggestion are more than welcomed.
