DNA-Guide 2

Rebound from my first Dribbble shot.

Working on my exam project in Industrial Design, at Konstfack in Sweden. One part of my exam project is a lifestyle application for iOS. The application is made for a swedish company within the fields of genetics (and therefore in swedish).

I'm currently trying to find a nice balance between "content and chrome", and therefore all feedback is welcome!

Also; is this kind of graph an understandable way of visualizing something?
