Who's is better My Mona Lisa or the original!

This is my drawing. As you can or can not see I drew the Mona Lisa. Well actually I traced it, but that was our task for the day. We had to trace the Mona Lisa and see the difference it had from the one that I traced. Yes I know it is missing the eye's, nose and he mouth but I didn't know what I could use to trace it with. Sorry for not adding colour because it is hard to add colour.Anyway I used the curve tool on google drawings. Does it look similar? Does it look good? I would say that it is kind of good, but I think I could make it a bit cleaner. I hope you enjoy this piece of art. 

My one I traced.

This is the original.
