Never use a pattern as a main background. The scaling of the render doesn't fit with the tag. Either mess with the stock size, angle, placement or mess with the dimension of the whole canvas. Try to avoid putting text on the very edge of your sig and vertically because it stands out WAY too much. If you need some ideas for background and foreground effects, just look up some tuts and get some ideas.
OMG It's the TWEWY version of Rikku! I really like the sig, it looks good. What website is this for? 8
It's pretty good but plain and the render really doesn't fit into the background maybe add some more brushes.
