That video certainly made it sound and look easy. Then I tried it myself without looking at the images from the video at first. Problems encountered: Unless I'm missing something, he does not explain how to arrive (how to construct) at the volumes for the planes he shows so I was still unable to construct an arbitrary nose from that (have to practice drawing random planes in arbitrary rotations first, heh).
So I tried to copy the planes he showed with mixed success. So well... some of the information he gave in that video is very valuable indeed, especially the bits about the underlying anatomy. I wish he would provide construction instructions as well, building up the nose from really simple volumes until it arrives at the detailed planes shown in the end.
Or maybe I expected too much, some sort of magical shortcut but there does not seem to be a way around detailed studies and maybe it will only start making sense after drawing a lot of different noses from real life references...
So, the following image shows me struggling to find an easy way to construct the nose, still not quite there yet but with the information from that video, already an improvement over my previous nose attempts:
