I like the hint of the building on the left; locks the viewer in, visually, and adds a sense of peripheral vision (as if in a speeding car). I also like the slight swirliness of this one - I am pretty partial to swirly landscapes! Also gives me fond memories of my trip to Boston.
Hopefully not in the speeding car while doing the actual painting (though that would be an interesting take on plein-air-speed-painting)! Excellent work.
