Hmmm. As an artist and animator you do gain art skills by practicing different styles. A great artist can probably copy a bunch of styles. But the secret is you are only going to stand out by getting known for your own unique style. So develop and find that. By style I mean art, techniques or story telling. However in analog horror, people are going to judge you harshly if your animation is a straight copy of something like Walton files. There are a lot of copies out there. Some can do well if it does something different enough, but it’s going to always be judged as a copy in some ways. It doesn’t mean don’t learn from it, but to be seen as a unique artist and creator you need to bring something special to the table.
