I wanted to be admitted to a 2D animation training so I tried to develop a less manga exclusive like style but more of a mix of everything I love when it comes to drawing styles
I totally understand what you feel, I still search to improve to a trully personal and original art style too. No artist just stops one day and say “okay, that’s it I can stop now.”
Your style will always change over the years, believe me, because you look at many artworks, you get inspired, you imprint styles and techniques, you learn new ways, etc…
I’ll tell you what they told me in class: your art style will often be a mix of 3 of your favorite art styles maximum. If you want to develop something unique, you need to learn from others too. Choose an artist you love and look closely at their works.
Some of my classmates spent 6 hours drawing non stop to try to draw like an artist did. What they did wasn’t to mindlessly imitate an art style though, they did it to analyze it.
By analizing I mean you need to understand how they work. You love how dynamic this guy’s art looks for example, try to see how he managed that, is it because it’s one powerful line to create a mouvement? Or does he emphasize on a curve? etc..
That way, you will imprint techniques you will lately incorporate to your own style.
Always analyze what you like in others in order to model it to fit your own art skills.
Also look and watch everything. animations and comics from any countries, movies and series can also inspire you with new colors/settings/angles etc…The art world is limitless!
You can do it!
