Hand-drawing is the basic requirement.

A jewelry designer can't do without learning to draw by hand.

How do you express your inspiration? What do you want to express?

So hand-drawing is one of the necessary skills.

If you are interested in doing this, but your hand drawing is not very good.

I think you can study further and see if your friends in Peng Zhong say you can consider it.

You accomplish what you want according to your actual needs.

I hope this helps.
