Again depth/blending problem. Like xdrac said, it seems like u just throw some stuff in there just like that.
If you have that much time then do not create sigs every 5 mins. Ask yourself, do i really like that?whatelse should i add? do i lack some depth in it?
Do not just throw some stocks in there and tadaa, im done. Work with it.
In that signature, if u wanted to change the render's color to blend in better with the bg u could use ctrl + u(hue/saturation) or gradient maps. KIU.
