Final stage, we will create shadows and highlights.

Create a shape with shape tool.



Warp the shape (transformation).



Use only 1 style and note the gradient blending mode - Hard Light.



The highlight has the same shape structure, only a little bit smaller size and Color.

Next select the circle (the 1st shape), create a new layer and overly the are with Black to transparency layer ( opacity about 70%).











Change the ball color (the color of the 1st shape)



Fix all the mistakes done when painting (if you have no, then it's ok).



Merge the layers and there we have it.







Hope you learn some techniques and understand the vector (shaped based) style.





ENJOY!
