Erick, it works just fine in the center of the shot. Well if you want your signature to be the focal point. A watermark should be faint not at full strength. The idea of a watermark is to keep people from pilfering your images. Now if you mean you want to use it as your signature mark than that's fine. But it should be in the lower left or right. Not in the center. Again, unless that signature is your focal point.
