The glass looks good (no black refraction), the caustics came out good, and it would seem you modeled the wine correctly in the glass (which is a major issue overlooked by most who do liquid in glass models). Most fail to render correctly because of the refraction (note how when most people render wine in a glass the wine never seems to touch the inner edges of the glass like it should in real life)... so you did a good job there. The only thing is I would tweek the wood texture to something a bit more realistic, and the grapes - I know you're proud of them because SSS is a bitch to master - but they don't look quite as good as the rest of the image. I did a still life recently and just excluded the grapes because they were pissing me off so badly. LOL! Keep up the great effort.

Cheers ! i like the glass and reflections! good luck!

Thanks for the comments. I'll be adding more to this composition later. I think I'll take the grapes out and make a different comp. The liquid in glass was done with kind of a cheat. I took the inside edges of the glass and detached them. Using that, I flipped the normals and capped it. I then put it back in the glass and scaled it a bit so that it "penetrated" the wall of the glass itself. Both of these items have correct refractio IOR's. The wood is being worked on, but I think that not much of the table will be visible in the final comp.
