Paint.Net? Ah maybe that's why your sigs never have effects they're all brushes. Paint.Net doesn't have much for effects and distortion. The styles are different and each have their own, but on DA people make much more brushes for PS than P.N :S
Oh well GL anyhow. I've seen people use this line format for sigs and make it look really well, but you could use some practice. The lines are just too... you know, too bland.
