ArtStation would is a great resource for a portfolio. You should only include your very best work. Don’t post work in progress work in your main portfolio. Make sure that you post only high resolution images of your work and try and create work that is targeted at the companies you are interested in applying to. Where possible include breakdowns of your work that give essential information that indicated your understanding of workflows and pipeline. Its always good practice to seek feedback on your work from practicing artists and there are lots of communities where you can engage other artists.
