artstation
A career related website that I enjoy visiting is ArtStation, a website where many professional artists post their arworks. The site is a great source of inspiration for me and other artists since it contains a very diversity range of arts, from illustration to 3d-modeling, animation, desing, traditional painting, and many others. It also has an online shop to buy prints, books and resources from the artists that sell them in this site, as well as courses and free tutorials that are organized depending on the subject, software, and skill level. They also have a blog section where they interview professional artists and write about the entertainment industry, so it's kind of a more professional social media than the more common ones, which makes it great for making an online porfolio to be provided when applying to a job in the entertainment or desing industry. I visit it when I need inspiration or I'm looking for a resource or tutorial to learn more https://www.artstation.com
