I agree with the gradient comment-it is a bit distracting. I'd try reversing it (making the light part near the house and dark away from it). If I see it correctly, the gradient is light in the middle and dark on the edges? This seems to give it an odd 3Dish look to it and gives it depth which is somewhat distracting.
Or maybe my eyes are deceiving me. Either way, I think the blue gradient could use some tweaking.
Other than that I REALLY like it. Simple and elegant, and the integration of the 'P' is icing on the cake. Well done.
