Uhm, everything you see in my sigs is ALL brushing. Smudging, adding small drop shadow effects, I could broadcast it for you to watch sometime, but that's up to you.
Because I looked at your sig that says Scilman elitepvpers.com and the canvas is very large, and the size might have put your signature size in all over the top, but i guess it isn't, but just so it looks cleaner and less space is taken up.
Hey Scil, to trim the transparent pixels of an image, when in PS, i think it's either edit or image, then press trim, then just press ok. Voila, transparent pixels gone, making the canvas of the image the size of the actual image.
