Your problem, SuperSaiyan, is that your sig is too large. The other problem is that you're using photobucket, which automatically reduces image size. I guarantee that if you upload the sig
here (just in case it doesn't occur to you, I thought I'd better tell you to click this link) instead of using photobucket your sig will look fine. If I'm wrong then give me your ID and I'll send you 100Bil and 50k UU.
[spoiler]When I gave you my take on the issue, I assumed you were using photoshop correctly. If my diagnosis is wrong, though, then you've shrunk the render or sig without constraining the proportions first. In other words, the assumption at the beginning of this paragraph is wrong. When you shrink images you need to make sure that the percentage you are shrinking the length and width by are identical - length and width percentages are near the top when you're in photoshop in case you didn't know. Check the box beside the length and width, which should say "constrain proportions", to do this automatically. Reinsert the render and constrain the proportions when you shrink it.[/spoiler]
