Chatting App Marketing Site

Continuing to tighten up the design/typography for the Chatting App marketing site before launching next Monday. The design follows a mobile first responsive approach which was pretty cool to code. I'll put the link up publicly when it's available.

What would you change?

EDIT: El woops. So the screen I loaded is directly from the coded marketing site, looks kinda crunchy so I've attached a big version.
