Another thing, in my opinion, would be to lower the noise, especially on the background (perhaps use a totally different background? subtlepatterns.com has some cool examples).
This is the first thing that struck me – you have a noise background everywhere and it’s too strong.
Keep at it, if this is your first design, it’s pretty good to be honest.
Every one wants to have the prefect design. Your design is really nice but think needs some modifications like extra spaces are possibly including horizontal rather than vertical lists to better create space.
