plz can you give me instructions to draw more clearly and  more easily with well labeled structure of brain so that i can eaisly got it and draw it

First draw an oval shape and make its border a bit rough and draw all the diff lobes in it.

Make it a bit rough again or make it like a walnut.

Then draw the medulla and cerebelum. For the cerebelum draw a samll elliptic circle.

And from this circle draw the Pons.

You can now refer the diagram of the structure of the brain to make your diagram more vivid and labeled.

I hope this can help you.
