I like the colors on the sides and the larger reflection of the olive in the liquid. I would have liked to have seen just a bit more "breathing room" on either side of the glass, but nicely done in my opinion.
firstly, i thought this was a super clean image. well lit. then the blue and brown swirly sides led me towards the olive in the middle. nice composition. then the reflection of the olive with that red centre finished it off. 8. well done, and good luck, ads :o)
