Which method is used in this artwork?

[Aredua]

I found this the other day on pinterest. I wanted to make something in this style but I've tried everything.

Is there anyone who knows how to make this shape?

The artist has drawn the shapes and filles them with gradients. This is not done with 3D effects.

Hi,

You can execute your example using the Pen Tool and Gradients like Monika siad, as well as the Mesh Tool, and Blend Tool maybe also.

Here is a tutorial that may help you:
