When i was taught how to make sigs, it was taught to use a rendering black and white cloud filter as the background and brushing on that, each later alternating between white and black, al brushing layers set on overlay and to add colour to the brushing i would use colour balanaces.

On this site you seem to have a black backgroudn and brush on that, also your brushign colours sometimes arn't just black and white but have other colours such as red, blue, etc.

Do you know which way is more effective?
