I love reading cheat sheets like this. I definitely do not study them and stick to them religiously but they are helpful. One thing I’ve learned about body langauge in novels, is to not make too much use of them. It would be like overusing dailogue tags. The story would consist of nothing but characters’ body language, at least that’s what it would seem like to the reader.
With everything in writing we have to be careful of how we used it.
I found this one on Pinterest and there are more like them that include different body language you can look up.
