@Sticky:

Not bad, but I see some things:
Your firefox: Take away the add-on bar and the address bar and it'd actually look quite nice.
Also, titlebars - they take up space and don't really do much. You won't believe how much more screen space you create by disabling them.
Also, the top bar (I'm not sure what it is) is kind of busy. I suggest i3bar with only the essentials or tint2 if you want a beautiful and fully customizable bar. Also, disable bolds in your terminal. It makes it look much better :3
