Your job: Facelift of our Web application for Web Conferencing. Redesign all of the three screens attached, and deliver Photoshop files. We need all standard elements in separate layers or files including fonts for production by ourselves. All icons an graphic elements need to be redesigned. Designs similar to the design of Max OS/iTunes are preferred. We expect a design as professional as the Mac OS design. Not such a cheap and unprofessional design as the three screens have. Please provide references of your design expertise. Mock-ups of some elements are highly welcomed.
