Interesting, It’s more abstract type of picture.
I miss the sharpness of drops on the edge of the lemon (try to use the sharpness tool in your software). I wold put more contrast.
Those bubbles are great, and I like the composition with the lines of different colour. I see that the bubbles at the top look really sharp (although it’s difficult to tell without a larger image) so I’m thinking it’s your DoF from the top to the bottom, you must have not been parallel with the glass at the time.
It’s a shot I’d been thinking of trying, I had a play around with a lime on a light table a couple weeks ago too ;)
the problem with macro it the depth of field and when it is shallow it is important to pick the exact part of the pic u want to be shape for most impact and in this case i would have preferred the hanging drops to be the sharpest area…
