@James R - don't stress about negative feedback. I've had none from the various bits I've done over the years. I do think it helps to avoid making absolute statements if possible. There are a few things that stand (like, don't eat yellow snow) but generally there ain't many, especially in 3d. I try to put some kind of caveat at the start so I don't have to keep repeating it throughout.
If I ever did get negative feedback then my strategy would be to say, thanks, please forward a link to/explain clearly your superior efforts, I'd love to see them, I know I am quite capable of making mistakes, & appreciate the opportunity to learn. Now, I know from retail work that excessive politeness can
really upset people who are looking for an argument, but if they do have something to teach, I can improve & then plagiarise the hell out of 'em. Either way it's a win
When I make a PDF I plan, plan & then plan a bit more. Writing things down helps me; section headers, phrases, info dumps etc. I work out what screenshots I'll need & where they'll slot in; I read out loud what I've written to see if it scans; I look at what renders I can add to make it visually interesting; I view the whole thing as an artwork in itself & that stops it from being too much like work. It's publishing, which I find nerve-wracking, but it can be quite satisfying.
So I say go for it.
