I often use a complicated flower pattern for my digital illustration. And I would like to share you how to make one in an easy way.
There are two types of flower patterns here,and I will let you know how to draw these in a most easy way.
1: Make a circle,and color it with spectrum color.
Select the twirl tool, and change the circle to the twirl shape as the photo below.
Then copy the shape;now you made a two twirl shapes with the spectrum color.
Next you will change one of the twirl shape color to the lighter spectrum color.
2:Selrct the tow twirl shapes, and select the rotete tool, and make a copy repeatedly.You can copy the shape every 15 angles.Then you can make a first complicated flower pattern.
Congratulations!
3:Let's make an another complicated flower pattern. You can use the same twirl shape in above tutorial.
You can move one from the first complicated flower pattern.You will change the shape to crystallize shape;Select the crystallize tool.
Then select the roted tool and make copy repeatedly as the first complicated flower pattern.
