Dragon, I strongly suggest following the tutorials that Rave posted for you. They will definitely help progress your application along. Also, please remember that we are all designers, we can tell what your doing with the images, no need to explain, we are just helping you take your current signatures to the next level.
When a designer gives you advice, it is best to follow it. Pake the nessecary to your signature and post it back up. It shows us that you are serious about you application and are willing to work with us.
If you dont mind, please pick one of the 3 tutorials posted by Rave and follow it. When your done, let us see the results. =)
