This is an amazing piece of photography with a great concept. I love the composition of colors and the bottle itself. However as some of the other critiques have also stated there is a flaw in the blur and parts of the bottle such as the cork and string should have been left sharp.
If there should have been sharp focus on the bottle and the background blurred to this extent then this would have been completely stunning.
Overall I must say the concept for this photograph is amazing and very original, all you need is a bit more focus and it would have been the most perfect photo. Great work!
