yes i was saying bl
ending, sorry for the typo.
now to explain the bkg thingy.. check the marks i added, there are 3 colors; red, blue and green marks.
1-
Red: Those parts are not neccessary, looks like a calcified stone. Try instead of that add wavey "liquifying" effect to that part of that layer. and faint it abit.
2-
Green: Empty space with no such meaning of completing the banner. So either make the bottom of the sig similar to the top (having black and white curve) or as i said, make the banner an oval shape instead of squared.
3-
Blue: looks to me like a human arm. But really it has no meaning that shape at all. Easier way to resolve it is to erase that part of the layer and maybe try and add star/ or whatever pattern you would like to add on both sides of the banner (with different sizes too).
