|Greetings from the Critique Club...
I was not able to vote on this challenge, but if I had, I probably would have given you a 5 or 6.
For the most part, I think this is a good image. The bokeh is really nice. I like the variety of colours in the bokey, and also how they overlap. I like the low angle you have chosen, especially since it leaves all that negative space up top for the bokeh. The focus looks pretty good as well. My only real criticism would be all the reflections in the glass. It's not so much the highlights, but the other areas of the reflection I find distracting. I have not shot glass before, so I can't offer any expertise on how to improve on this. Cool shot.
If you need any clarification on any of my comments, please feel free to pm me. It might take some time for me to get back to you.
