Telescope - Design Firm Directory

This is a UI mock up I'm working on for an online directory for finding humanitarian design firms. I did the icons from scratch, and the search bar as well. This is just the home screen with more screens to come!

Any and all feedback would be greeatly appreciated. I'm trying to get some critique on this, so any pointers or tips would be of use...and don't worry, harsh is not in my personal vocabulary ;-).
