I think that if you had close up more to the bubbles, it will be more aproperate to define it at Macro/Close-up.
Oso, the reflections off the bubbles would make it better.
The background (the spoon) give a very ugly contrast to the subject (the bubbles). If it is just the bubbles in the cup(whatever it is) and have the reflection of the spoon in the bubbles, I think it will make a superd pic!
