The objective of this contest is the design of interfaces of a mobile application. I have attached pictures of two interfaces (billboard and user profile page) that need to be redesigned. The final design need not to look exactly like the sketch, so you can change the layout! The winner of the contest will also redesign other interfaces. Important note: the color schemes are yellow and black but we are opened to new color schemes. You can also provide us with the tab icons for the billboard page and the user profile page. The icons should not be too standard!
