Very rough though, especially visually. You might keep in mind that it's best not to use multiple objects where one will do the job.

This also feels a lot like three or four mini-maps rather than a cohesive whole. Try not to incorporate vast amounts of ideas into one map -- instead, favor one idea that informs the whole map, or a series of ideas that work well together. Otherwise you're left with something that feels disjointed and messy, kind of like this does.
