Hi,
The images slants down from left to right, this is a straight no-no.
The original image is too dark for me, I'd prefer to see this exposed more before pushing it through LR or PS. It's also a bit warm, there is tint in the white chips that shouldn't appear there. I think both these points reflect on the final image.
I'd have arranged the objects in the foreground differently, they are very much on one line across the frame which looks unnatural. This is a pity because the light reflecting in the decanter and tumbler could have really added to the final image if they had been placed differently. This might seem like nitpicking but for me it's this attention to detail and the little extra time it takes that makes a great photograph.

P.S. That's a fair measure of whiskey you have going there....and that's coming from someone who's Irish!
