I looked at all of these, as well as, earlier today, all of your fairlty recent summer shots of the D train, etc.. I can give you one piece of constructive criticism: your approach to framing and compisiton needs a major re-evaluation regarding how much "top space" you are allocating in your people shots! The amount of top space allocated above the head of a person gives me a very good idea of how much a person has studied composition. Ever shot in this post that has people, has the people "riding way too low in the frame". I'm not sure that you are even aware of this problem, but it is severe. You are dojng much,much better with trains, however, probably because they are extrmely well-suied to horizontal compositons and horizontal framing.
