Overall it looks rather nice! The choice of pics is great, and you have definetly created a point of focus, being your centre piccy. The text you used, and its "box" thing work quite well with the sig as well. The one thing Id suggest to change is, like ^^^ said, either make the boxes blended into the bg smaller, and a little more transparent, or just make them alot more transparent at that size. Otherwise its some nice work!
