You asked for your shot to have an in depth comment from a member of the Critique Club.
Cool shot, it is something completely different than what I thought it was when I was voting.
The only thing wrong with this shot is the focus and you touched upon that in your comments. I am not sure if unsharp mask could have helped any here, but it is worth a shot. Flipping the shot may have been interesting too. There really is not a lot I can say about a perfect picture that just needs one thing sorting.
I love how the smooth curves all compliment each other, the red is very sensual, I could stare at lava lamps for hours.
I thought the focus was going to doom this, but it came in fairly well. I suppose my pre-challenge feedback was too doomy & gloomy on this one. Everytime I think I have it figured out, I am surprised. (Of course, I did not vote on this.) Good going!
