Messing with reflectivity and transparency… I’m quite a beginner so don’t be harsh 
I need some help with lighting. And the glass and ice too.
No comments? Please help 
Nothing much from me as I’m a beginner too. I would do a harder specular highlight on the bottles though. And I’d also add some texture to various things like the tin foil on top of the bottle, the cork, and the ice cubes maybe. Good luck!
