/ic/ - Artwork/Critique

do you need to know all the art fundamentals like construction for example to model and texture paint low poly 3D models?
i just want to make simple half life 1 or warcraft 3-esque textures but feel like i must first complete a book or three on fundies before making my own stuff.
i checked some of the texture assets for both games and it seems like beyond basic understanding of textures/details, shadows, and color theory there's not much else to it but practice. what do you think?
