I agree with pingking23 about the environmental effects
Plus you could also add some distortion at the bottom {where they join} tines of the fork
You can see in the reference that the surface of the fork is subtly curved {probably because of the way it is made}
Either model this, or add it as displacement or bump map
Fix the geometry; the deep corners look flawed and there is a dent in the outer “bow” (? near largest width of the mouthpiece). Looks slightly out of proportions, but I can’t put my finger on what.
Material; avoid using a mirrored texture. Vary everything, if just slightly. Try to match up what is actually reflected. But yeah, I agree, I think it’s the reflections/environment that is the biggest culprit.
