This is a peek at the basic look/feel for the app I'm working on. I am loving the dark UI, but I'm a little concerned that it might be too dark/heavy. What do you think?

P.S. "Iconica" is a simple placeholder for the company name, which will be revealed soon. The word has nothing to do with the company, however the green is the company's primary color.
