Thanks! I was tried some more opaque highlights, but I wasn't happy with the way it looked. I can see what you mean about the colours, especially in the lower half :/ (I submitted it on the last day of the contest so I tried to wrap it up as fast and best as I could)
Holy shit, this looks amazing! I absolutely love what you did with the light and the contrasts. (also I've a bit of a weakness for fictional jellyfish haha) Also I think the jellies carrying the fish is quite a neat concept. Overall this is a stunner.
