Nope, the shadow makes it; maybe darkening the lower parts of the main pic would give it a more balanced weight? It seems to me to be fading as the eye drops lower, making it feel oddish - to me, but that's no guarantee of anything! Were it a print, the temptation would be to shade it in from the bottom right up. In fact, I think I'd darken the whole thing, regardless of what the original might have been.
Love old materials like that - but remember, no saws and no jars!
