Nice to see some real chemistry in this challenge ;) I like the whisp of smoke and blue background - the highlights and pipette are a bit blown out. Good composition.

Highlights are a bit distracting, and it could do with greater depth of field.

I like the capture of the smoke, but the pipette tip is a bit blow out.

With knowing some of the things HCL can do, I would have expected something much grander. But you do have a nice graduant and lighting seems to work except on the cap and top edge of dish.
