K, the refinement for the icons.

From the suggestion in here and Facebook, i change the base to remain the consistant of each and every vector icons; and also added tv antenna on top of the house to make it looks like a house.

pixel icons i just tune down 15 of the saturation of each icon for the background. not really much different when view it in large size, but when it comes to original size then you can see the difference. hu~ done. thanks again everyone =) appreciate!
