The Greatest City In America

Still in sketch mode here and desperately need some formal and comprehensive feedback! Legibility is huge. Consistency and flow are also concerns, as is spacing and weight.

Letterforms that need the most help:

1. "y" - City
2. "n" - In
3. "m", "i" and the second "a"- America

A piece of your mind would be greatly appreciated. Please weigh in with any suggestions...
