All what everyone said is right, however everyone does what SheEpy does, where as SheEpy just comes out and says it, other people say it not as harsh, also they put something that's good about the signature so they don't put the person down. Try to do something positive followed by a negative SheEpy, also don't say the negative as harsh as you do now.
ONTOPIC: I like the realism effect to this sig. but one thing lower down the intensity of the light. (dunno if that's the right word.
