I added wind, cropped, liquified, blured, added a cloud and ummm text?Explain what changes you made. Looks good except the text.
Nope, first timeI like it. YOu should add a border if you want to give it a sig effect and you need to change the text. Resize it a bit and it could be a neat sig that I would use (I have mine so not using it).
Have you had any previous experience with PS?
