I need help designing a UI for my game (UI mock-up)

Design details: I'm designing a 3D real time strategy game for the PC called 'Shallow Space,' I need help re-imagining the UI for a part of the game. To start with I require a mock-up to explore the various options available arranging the placement of the icons for usability and filling out blank space with seperators and UI hints. Two images are attached, the first is the UI as it is currently and the second is a UI we would like to mimic.

Once a decent mock-up has been received further work will be needed to creating the UI elements to be used (such as buttons, retaining panel etc.) and creating 50 or so icons to replace the placeholder icons. So it would be helpful (but not essential) that you are able to work at this level.
