Style develops like a nickname. You get one over time……If you have to give yourself one, you’re a dork.
It will come from trends during your formative years, what stories you liked, what stories you didn’t like, movies, TV, people in your life, comics, colors you observed as a youngsters, whether you are introverted or extroverted, your teachers, your bullies, everything you imbibe as a person will eventually get used as art in some form. That’s why it’s important to live life, it will reflect in your arts.
As far as favorite artists, most of mine were directors and storytellers. Not “artists” in that painter/drawing way. But if I had to shoose an artist, I loved Bill Watterson. Both as a storyteller and as an artist and human being. He knew what was personal to him and what motivated him as an artist. And that’s hard to maintain. Integrity. You only get one reputation in life, and I thought his was top notch. So he’s probably the biggest for different reasons than the art itself.
But I took it all in. I never looked at any one artist, just cool ideas I liked. Which usually came in the story part and not necessarily in a particular drawing or style.
I very much on purpose quit drawing from other people’s art because I did not want to be influenced. I even remember putting away art of books and comics in high school so I would struggle more. It worked out but it’s not the path for everyone. just mine. ;)
Hope that helps.
