did you use cycles? That will (can) make it look more photo realistic. Other then that, make sure your pen has something to reflect, and play with the lighting, samples, and shadows.
what i would do here is put a plane in to act as a floor, it can stay white. also use environment lighting (you seem to already have a sky texture set up), make it brighter in general, and make some bump maps for the brand name and the little ridges on the clip thing.
@Max11D : I have already added a plane to act as the floor and added a HDRI to the Gold and point of the Pen.
Yeah it looks better with enviroment Lighting!
@Place57 : No i didn’t use cycles, Actually never used it before might look into it!
Il play around with it.
