Devarium Brain construction grid

Hi folks !
Here is the first try to create a brain in vector combining the technologic side of left brain (line chart, isometric shapes, like printed circuit...) with the creativity of the right brain (round shapes, more organic)

I'm not really pleased with the right side right now, i'd like to create something more "plain" with bright colors to express the "out of the box spirit".

I'd also like to create more connections between the two sides... Any ideas ?

(And yes, the red side isn't really on the grid, it is more "floating")
