Desktop Chat Application concept for UI/UI designer

Tengja- It means 'to connect' in Icelandic language. This application is a chat application for desktop and mobile devices. My desktop page version with so far progress is here. The motive for this app is connect all UI and UX designers ( individually and together as well).

Here is my behance link for this design page. I am going to create the design for mobile as well.
