Showing the metaphor from the original poem in such visually explicit form feels similar to when someone uses a hypothetical situation in their argument, and the person listening focuses on the details of the hypothetical situation rather than the original intent of bringing it up.
Still, establishing the vibe with the music, colors, illustrative style, motion, and asset-making priorities in reference to the poem is very expressive of you enjoying the poem deeply, and I like that a lot. I enjoy your enjoyment.
