Not the best

[Kryptonite]

I like the signature but it's kind of choppy I don't know how to get it smooth.

[Headshot Jr]

all i like is the Abstract Bacround, Other then that the render i dont like and the Text well its ok

[GoldenSun]

It's just a plain abstract bg with text + stock slapped on to it. Spend more time on your sigs

[Kryptonite]

I may think of something better later on today.

the render in the sig is hughe make the render smaller so he fits almost in the signature and blend the render in it..!

I don't see a reason for this stock to "pop out." Maybe check out some tutorials here and try to use the techniques you learn to create your own style.
