If this really is your first signature it's pretty look at my first signature lol it failed (down below, i'm using it right now, haven't been bothered to make a new one for myself) but like thersgod said, the light is too bright and you need to remove the black background, if you have trouble with removing it pm me, I had tons of trouble when I first started but anyways, try to make the light a little less bright, and also try to add multiple lights, rather then one big points of focus.
