In the art world there's hundreds of styles unique forms and techniques. There are many artists well know for their own style. If you want to become an artist with your own style, you should develop your skills, get inspired and work a lot.

How & Why to Improvise?

Find an inspiration
Everyone's style is influenced by another's. Find a good artist that you admire, "shadow" their work by looking at how they draw their bodies, proportions and how it works together overall. This way you can see the mechanics of their style.

Add some unique details to each painting/drawing
What are some line styles that you are comfortable with? Sharp, quick, pointy lines that feather out? Smooth, round, bold lines? Jagged edges, and pointy features? What lines make your art yours? This is important because your lines are what makes up the "mood" of your style and the "mood" of the characters.

Keep a Journal/Sketchbook
Never go anywhere without some method of recording flashes of inspiration, whether it is a journal, a sketchbook. This is helpful for recording ideas as they come to you, so that you don’t have to wrack your brains later and waste time “being creative” to come up with a new idea.

Draw, Draw and Draw
Drawing is like a basic in every kind of fine art. You must develop your drawing skills to the highest level. The more you draw, the more you get better. After all, who doesn't want to draw?

Try to play with colors
Make your painting a beautiful fairy tale. Play with the colors. Don't be afraid of using the whole palette. Sometimes you don't know how its going to end up, but try!

Get On It
Grab some paper, a pencil and get started! Start doodling random characters using the line style you chose. Experiment by varying the size and shapes of limbs and features, and placement of things. Despite the fact that an artist's style is never truly complete, after much tweaking you will soon be in a place where you'll be happy enough to public share your style!
