My only nit-pick is that I wish you had showed the front label on the wine bottle instead of the back. The back one probably isn't as pretty. Cool idea. I love that you put wine in the vase.
Interesting that you chose to show the back of the bottle. That's much less appealing than the front label. Couple that with the uninspiring background and you have an underwhelming image in my opinion. I hope these comments help you to improve.
