It's much better than most of my drawing of people...... ...by about 10 times.

There is nothing wrong with your art. Sure you probably wouldn't be able to sell it to the Guggenheim but that is also not really a realistic level to base the quality on...I don't think you could sell it to Louvre either.
I have to say that I really like your style of drawing, it has this ash can/grafitti feel to it. Definatly keep sketching. You can only improve from here.
