I need someone to improve my website

Hello! I'm an artist who owns a YouTube channel where I share art, garden DIY and recipes. I have other social channels as well and my own website, which is currently not getting much traffic nor sales. I believe it needs some refreshing/optimizing and I'd like to have that done.

My site is hosted on SquareSpace, but I'm open to migrating it if you consider it necessary. I'd love to hear your thoughts.
