Time for a little old school insight. There really is no "perfect sig" or even "perfect" way to go about it. The most important aspects to me are originality and continuity. For example, a certain font may look perfect with one design and then completely out of place on another design. The most important part is making sure the text, the background, and the images go together smoothly.
