This theme is designed for use with global menu, a #E1E3E6 gtk bg, and fonts with similar sizes to the ones shown. Everything on the panel is not included but the effect can be easily replicated by following my link bellow. Mostly by adding the panel background, patching gnome-panel, and window-picker-applet to use icons a few pixels smaller than the panel.
Dependencies: the Nodoka engine

Credit to the Nodoka guys for the Improved theme which my theme is based on, and the Elementary guys for gGTK's nautilus work.
