I'm finding this quite hard to comment on! I like the backlighting and it def. meets the challenge.
I find the content interesting but partly because I have no idea of what it is and i just keep staring at it trying to figure it out! I'm assuming it is a cat and a vase?
What I would have like to have seen was a bit more detail on the 'cat'.
The cat shouldn't be there imo, it just distracts from the "fish", which I think should have been smaller (and not cropped) so it would have been easier to see the shape of it. Funny title.
