I don't know how the heck I missed these images of yours last December, Rachel! I'm so sorry...they're right in my back yard, too! Of course that's Wabash Avenue with the el tracks, just south of the (red) CNA insurance building. A favorite haunt of mine, particularly in September and October afternoons when light plays magic with the shadows and colors there. The city's oldest (and one of the few remaining) camera store, Central Camera, is just down the street past that "Park1" sign.
You've picked a terrific location, Rachel. Too back you didn't have more time to explore it further. (Sigh...Families and cameras don't mix.) Your images are good warm-up shots that would help to get your eyes limbered-up to shooting. I've literally spend whole days working along Wabash from just south of your location, where the el curves, to Lake street where the el makes it's other turn. The challenge here is making decisions between the atmospheric scene, the geometry, the bustling street (which isn't bustling at all at the time the shots were taken...but normally is filled with students and office workers), etc. If you visit again keep these choices in mind. I think they'll help guide you.
Again, sorry I missed this so long ago.
