I've been invited to give feedback to all Parsons students, regarding your thesis projects.
I like that you've considered a frequently used and oft-ignored public space as the territory for your design solution with Subwait+. It could use a dose of beautification, for sure. And considering the emotional needs of those who wait for subways is a refreshing human-centered approach.
However, your problem statement and proposed solution are missing some key pieces, like cost and how the system will be distributed. Are you focusing on all subway stations, or just one? Are you thinking about who will generate the sound and images? Perhaps this is an opportunity to feature student work or up-and-coming local artists? Or maybe it's the musicians who busk in the subways themselves?
Fun idea. Give us a little more to chew on though, and consider the expense of the technology and who will fund it, etc.
Thank you! J.
