Bonus points if the author first mentions a specific trait, physical build, or whatever else halfway through the novel and totally fucks up my mental image.
I don't expect a biology model description for each character, but write me something brief and evocative of how they should look, you fucking dork author. I don't even know how tall she should be, her hair colour, anything. Why are you like this, author?
This has always bothered me.
This really gets my goat
I think a rule should be, if you are gonna describe, do it early ffs.
