How to simulate the cloud to the shape of the reference

[limlim]

We need to do a similar effect in the project, but I don't know any good way to simulate it. I feel it is difficult to control only by parameter adjustment.

This effect needs to be layered inside, from the very small edge at the beginning, to a large number of small tumbling in the back, as well as a larger tumbling form in the back. I wonder if there are some big people who can share some experience or production ideas, I would be gratefu

Try with smoke and light it from the top maybe ?!

For Example:
