Here is my rework of the one you did, hope you don't mind me messing with it.
I trimmed the edges down, just because you can have a large image doesn't mean you should. Small looks better, and says I can convey my message without exploding your forum.
I removed your text and replaced it with my own. The smaller one made in Arial because aerial is easier to read when it is that small. The Angels logo since it was large used the "Title" hand script font. Now this logo has it's problem still but I tossed it together in 15 minutes so it isn't perfect. I also took the moon and made it pop out of the signature always an eye catcher and it will lead people to the angel hidden in its surface. The glow on the moon is kind of cheesy if I was going to make this for real I would change that out. Also the logo could use some more meat to it. Make the image a little hardier and solid.
