The previews don't do justice to the artist and their work. The animations are quite good, they are rendered and animated well, it looks realistic and stays true to the original art-style. Most of the collection is Life is Strange, but there is some Overwatch and fewer videos of other stuff as well. Some of them do have audio, but these are done by other people. Give it a try, and support the artist if you like their work, and are able to.
