How to draw bubbles

The drawing tutorial of bubbles is as follows:

The first step is to draw a bubble shape.

The second step is to draw the bright part of the bubble. If it is an umbrella bubble, there will be two reflecting surfaces (outer and inner).

The third step is to draw a dark part in the opposite direction of the light source, and the dark part should consider the reflective background.

The fourth step, considering the color of the environment, add the color of the object to the side facing the object.

Step 5, correct and adjust the color block shape.

Step six, adjust the whole picture, adjust the color, contrast color and brightness.

Experience is for reference only. There are still many ways to draw bubbles. You need to practice constantly to find the one that suits you best, but it is also necessary to pay attention to small problems such as dark parts, highlights and reflections. I wish you early success.
