Thousand Wires Navigation

There are two things I'm looking at here, three if you count the color which is still up in the air... The first is whether or not the icons make sense for my app. I don't expect them to make complete sense here, because it's so out of context and they relate directly to pages of the app. The second is the subtleness of the divider bar. The four icons on the left act as project navigation whereas the three+ on the right are global options. It make sense to me, but I wonder how much of a mental hurdle it will be for my users.
