If it isnt broke, dont fix it I don't want to go back to the same sigs.. ala.. Render with a background. Editing a stock image makes it better because there is so many possibilties with what you can do. For my next sig i can add brushes, add a new pattern, make a different gradient map, cut part of the image and place it somewhere in the picture. I'm happy with this style.
ur missing the point, i mean just Try something different and see if you prefer that, Anyway, can u send me the link to the tutorial? some stuff could be useful.
