Marilyn Monroe Sketch made my friend

I am not an Artist and don't have much know-how of art.

I have a friend and she made this sketch and I was like wow man, it is so good.

I think she has made a good piece and on top of that, she has drawn Marilyn Monroe who is a legend in herself.

So you guys tell what do you think?

If She can draw well then I will ask her to draw my sketch. So I am betting my sketch on you guys.
