Yeah they want the portfolio page to have a style where each section takes up the viewport height. If you make that adjustment I think it will look ok.
The documentation page works like most people in that the last few links don’t scroll the page further. This can be solved by adding a blank section at the bottom with extra height. Late at night after reading lots of docs it sometimes feels like work to stop and figure out where the next section is if it’s visually far away and my window is tall. Other times it’s close by and doesn’t matter.
The ROG page has the same problem as many other peoples do in that the nav scrolls the page too far. If you compare it to the documentation page the function is the same but now the very top of the screen is covered by a header. Here’s a way to stop the scrolling earlier.
On the Survey page I’d close the gap between the two columns. It’s better UX.
Overall you’ve done a very good job.
