Small points on simple drawings:
1. It is recommended to start with a pencil. If you make a mistake, you can correct it, and then trace it with a brush. If you contact me more, you won’t need a pencil to draft.
2. Don’t make the picture too similar, use your imagination, exaggerate and deform it...
3. Drawing is a very happy thing. Painting is not about how good you are, but how much you like to paint.
