Golden Sphere - Blending and Shading Practice in Procreate

Slowly I am practicing different techniques in procreate.
The most challenging one for me is blending.
I was trying to figure out the brushes and techniques for blending.
But it's still difficult.

The opaque brushes and building colours is a big challenge for me.
and that makes blending and shading difficult.
Require a loads of practice
This golden sphere is my first attempt.
