Every signature needs consistency, meaning that if you have one image with a lightsourc eplaced in the upper left corner, you can't have a second image with a lightsource on the upper right.
In your case (and I'm referring to your current signatrue of Jin), you have the ugly lightblob in the upperright corner, and then you have this image of Jin with a lightsource in the upper right corner. Explain please?
In either case, the lightblob screws up your signature. Get rid of it or use it more wisely, but not like this.
