Portfolio for 3D modeling?

Does anyone have an idea what site would be the best one for making a portfolio for a 3D modeler? Is it upwork, artstation or some other site? I need a website where anyone without an account can go and take a look at what skills I have.

Thank you in advance.

I think Artstation might be your best bet in my opinion, all the artists i look up to seem to have their work on it so it is probably the place to be at the moment.
