Break-dance Subway Design Sketch-Up 2.0

I have taken my initial sketch-up model and adapted it quite significantly. I felt that the design would be more interesting if one walks down the subway towards the train and then walks up the stairs to the platform on either side of the train. Secondly, I have had the idea of making the stairs to the subway more of a pier inspired public area therefore I have changed the staircases and I will begin to create the actual pier shortly. The last thing I have done to this design is add windows on either side of the subway in order to get more natural light into the area. However I am not sold on this idea, I have created a pattern for the windows to give a glimpse into the inside of the subway station from the exterior and make it a bit more 'funky' for the lack of a better word, however I am thinking about removing this and making it solely artificial light in the station like real-world subways.
