Really glad you are making these, thank you for all the thought you've put in! I think it will definitely help artists newer to these concepts and some of your process descriptions are very concise. I'm sure as the series goes on I'll pick up some tidbits I didn't know about too.
That being said, I have one major (hopefully constructive!) critique of the series so far: node graph organization.
Please take this in the most polite way possible, but I think this is setting a very poor example of Flow organization for artists not already familiar with large Nuke / Fusion style graphs.
Just like reading text, nodes should generally "flow" from top left --> bottom right. Inputs start higher than their outputs, merges are below both FG & BG, etc. The primary trunk of the tree runs straight down from the main input. New inputs merge to the trunk, additional operations on the source footage branch from the roots of the trunk and then merge back in.
This is a Nuke chart so the left / right principle is less important than top / bottom, but you get the gist (in Fusion I find left / right consistency is often equally important):
Optical effects take place at the final stage of the pipe, followed by adding grain (as the very final step in most cases so the grain does not become manipulated by other operations or transform filters).
Labeling nodes is great and should be done anyway, but a well laid-out node tree should be skimmable at a zoomed-out glance without a single label so that another artist can at least identify things like order of operations and inputs, and then pick out more specific organization at a per-branch level by looking at masks or trackers.
The top --> bottom vs. left --> right debate is mostly preference, but whatever you do it should be consistent, not changing directions from one operation to another.
Anyway, I hope this point is taken in the intended constructive spirit -- very glad someone is popularizing Fusion beauty techniques. I just think setting a good organizational example will help the whole community in the long run.
