I can teach u

That’s really cool btw

Ok so let’s say u choose too shade a blue ball

U get a dark blue and a light blue and one in the middle

U get the blue in the middle and make a circle with it

Imagine where the light sores is and put a showdown on the opposite side of the ball

Shadow*

Get the dark blue and set it to Somewhere around 0.20 opacity then Draw it on the ball on the side of the shadow

Get the lighter blue and set it to around 0.20 opacity and draw it on the ball closet to the light sorse

Then the trick is to shading

It is that u have to blend the colors to make it look good

Also I wouldn’t have the outline if u want to be better

Oh also just practice look if u practice eventually u will be this good ——>>>
