Art resources
While this is called Art resources, you probably won't find links to step-by-step guides, rather the places I frequent for inspiration. The following links contain several content I've used all of these years, I tend to not follow tutorials, I mainly like to improvise, yet, I highly rely on references, anatomical illustrations, and science fiction. Learning about art also means you must expand your own mental library, read, new experiences, learn about other's lives, educate about different cultures. I'm deeply fascinated about the different worlds we all live in, it helps me to be open to different point of views and ways to manifest yourself and self expression.
