The task was to make a UI design for yet another one transfer file service, which was based on a well known practice of other, already successful services. Client wanted to keep the business logic, but to have a slightly different touch and feel.
First solution was built around idea of progress "bar" info. We introduced colorful smiles and tried to design around them a whole interface. Client actually liked the concept but raised a concern about user friendliness of smiles, especially of a "annoyed" red one with a flat mouth expression. Agreeing that concept needed further fine tuning in a way to be found a proper balance, but since was no guarantee of successful outcome in a tight time frame, we put it aside for a while and turned to a different approach.
Second solution was based on a idea of a box, presented in a isometric projection. Having clean and geometrical approach, decision was to build an minimalist and suggestive interface, based on a polygonal shapes, circles and lines. Very reduced color palette served to promote an idea.
After some thinking client expressed the worry that it looks almost to clean, cold and maybe hipster, so we had to return to the first solution, and give it a second shot. Since client loved the pale blue, we kept it, added a dark gray instead of black and changed UI elements to be more mainstream. Another requirement was altering the logo in a way to have more connection to the "cloud"...
