Language Exchange App Mockup

A flat conceptual mockup for a language exchange app I'm working on (http://linguistic.io). This mockup specifically focuses on the chat window, with the conversation displayed on the left and chat partner info on the right. If the user desires a new chat partner, they click the plus button in the top righthand corner. The bell icon lights up when a user has notifications. Tell me what you guys think! I'd like to give a big shoutout and thank you to @Brian Talbot for the Dribbble invite. Looking forward to sharing my work with all of you talented designers!
