When I say composition, I refer to your sig in its entirety, like for instance, a person's compo can be good if it has good flow, consistent posture and effects and sweet lighting, where it can be bad if it has abrupt flow, chaotic effects and clashing elements and bad lighting. See what I mean? So in your case your compo isn't bad the smudge needs to be consistent, also watch out for your blending and color and contrast. Thats what I meant by composition.
