I’d say that “you got it.” I could be convinced that these are real tubes of product.
But – I think that I would compose the shot with much fewer products in the shot. Much tighter. Focus the viewer’s attention specifically on the several different “key variations” (or, product subtypes). Leave the models exactly as they are.
I think this is a great start and has loads of potential! 
If you don’t mind I might have a couple suggestions?
- Have all the same product apart from the one right in the center.
- Have some stronger lighting which will help adding some contrast to the render.
