Was this maybe supposed to be in the comfort challenge?
I like the star on the glass but it is to deformed on the bottle.
The table is shining clean on the near side makin the bottle look bigger and therefore the placement of it seems wrong.
Nice composition.
Some tips:
1. Background looks a bit distracting. A single colour would help
2. Glass looks better when perfectly clean
3. Some sharpening would help
I'm unsure if the slightly soft focus is intentional or not, so I'll assume it is. Having said that, whenever I see a glass of champagne (or a glass of something which purports to be champagne), I want to see crisp focus showing rising bubbles etc.
