Some points of feedback to take or ignore.
1. art on its own is so broad that it's hard to grasp where to go or what resources may be relevant to me on the home page. I may not be the absolute beginner you're aiming for, but at the same time most people looking for inspiration or resources usually search for "drawing" or "painting" and not "art" on its own.
2. The tutorials and guides in the store section look like a great way to learn at a low price. Nothing wrong with earning money from your work, but offering exposure to artists for a fee to be featured in a blog feels weird/icky.
3. The Instagram embeds on the blog don't work unless you click through to them which is annoying. No doubt IG has enormous influence on art/artists, but making people click through to another web site to see a blog photo is not a good experience.
4. The footer links under Artist Utilities should be on the main top navigation or somewhere else more prominent. Some really neat resources you have but likely missed by many because they're buried at the bottom of the page.
Overall I think it's a great idea to offer a mix of free articles/resources mixed with paid services.
