the reference image is of poor resolution but if you look closely you will notice, that there are no regular bulbs there, but some kind of small halogens or a bulb which is partialy nontransparent and therefore casts directional light ;)
you on the other hand used regular light bulbs and this immediately screams "fake"
but dont get me wrong, I still think that your images are great. If it wouldnt be those light bulbs I'd probably think those are photos if I'd see those on the internet :)
