I see that you use stock's, and then put writing over them, its not really original, but to make them more orginal, add more effects, try other signatures types.
There was a Signature of the week competition on gamesignature.com, owned by Iceboy, where you had to use this stock, to make a signature.

Iceboy's outcome:

As you can see, they are all different, but all have unique features that the owners used, and thats what makes them original, try out some tutorails, and you can get much better. Why not have a go at using this stock, try some cool effects, and see what you come up with.
