Subway commuter sketches

I started the sketch on the left side with a figure of a man waiting for the 7 train to Queens but you hardly see it anymore because I overlaid it with the sketch of a lady.   The man on the right was most likely a musician.  I'm guessing it was a guitar hard case propped up between his legs.  I had a good look at him given the more defined features.  Soon, he stepped off the train.  Now, I was looking at the bigger sketch size of him than the man I sketched earlier.  To "fix" this sketch, I drew the lady's outline over the old sketch but her placement came out a bit off compared to him.  It's okay.  It's just a sketch practice anyway.
