This has some really good qualities to it.
What is most disturbing to me is the bottom of the bottle; it shouldn't be that flat.
And may be add some thickness to the label (use a Solidify Modifier on it).
There are more small things, like the scale of the marble texture makes the bottle look tiny. And how small is the room, compared to the bottle? but these are all easy fixes and they will make it a lot more believable.
Don't get me wrong, I'm just trying to help;)
spikeyxxx Thanks spikey! Yeah i tried to fix the bottom but i had some issues, and the room its just an plane with an HDRi around haha :) ( I will work on future fixes)
