Again, you can’t exactly “steal a style.” Unless you copy it line by line, detail by detail. If you compare two similar works between two different artists, you’ll be surprised to find some differences. All artists have to start from somewhere. I doubt your art style is completely original either. You can’t own an art style, that’s ridiculous.
Art theft is a totally different topic. It means you take someone else’s art and claim it to be your own. It doesn’t mean that a style of an artist is similar to another.
But don’t take offense from this, I just wanted to point something out.
