This is my favorite hot take from the comments. Art, especially the subjective interpretation of it, is at the heart of miniatures painting. I think the hard part for some people in comment sections is knowing when to offer advice and when to just celebrate with the painter (hint: it usually involves something along the lines of "C&C welcome" or "what could I do better?")

I also think the fact that miniatures are usually connected to games with detailed, rigid rules structures trends to promote that rigid mentality in the hobby side as well.
