>( I disagree. It looks awesome, especially the colours :3 But it still looks unfinished.
You still have some more AAing to do, there are still quite a few jaggy areas.
Your smallest bubbles on the right hand side come off more as lines rather than bubbles, I would either make them 2x2 squares or 1x1.
I think the leftmost jellyfish should still be pushed more into the background as currently it seems to compete a bit with the main jellyfish.
Maybe give your main JF some more breathing room and expand the top of the canvas by maybe 20~ pixels.
Also, perhaps give the main stem some stronger highlights. I think that would help make that area look a little less flat and it will add more coherence to your main JF. At the moment I feel the stem is a bit unrelated to the top part.
