I’m not sure the new rules will allow me to tell you to go here or follow these people to help you get ready for a job. But, at least in the US, having your own domain name (not Mr. Halls), portfolio pieces that are relevant to the companies you want to hire you, and building your brand go a long way to helping get you hired.
If you were to code the fashion nova site from scratch and turn it into wordpress and shopify themes. That goes a long way toward proving yourself to agency and e-commerce companies. Then it’s a matter of getting it in front of the right people (networking)
Don’t lock it down. Leave it open to the world.
