awesome man, i like it a lot. The only critique i could offer is that the guy in the background in panels 3 and 4 on page 1 is questionable because he is framed in black in panel 3 making him an important element for the eye to go to. In panel four he is moving up the escalator which is a movement that suggests the eye back up towards panel 3. I agree that it looks better with a person in the bg, but his presence is too distracting. I think someone sitting on the ground next to the pillar in panel 3, and a couple of girls chatting coming down the escalator in 4 would be circumstantially dismissive and not be compositional distractions.
--but mostly i just wanted to say awesome work!!
