Help / advice for another element to include in Fall themed irezumi.

Hello, Im doing a 3/4 leg sleeve and need some advice. Right now it has a koi going upsteam, 3 chrysanthemums, and I know theres at least 1 maple leaf (work is currently just short of knee). My artist said theres room for one more thing, such as another koi, but I was wondering if theres any advice on something else I could add that wouldnt detract from the theme?

I looked at this thread https://www.reddit.com/r/irezumi/comments/xmc3h9/japanese_tattoo_dos_and_donts/ as well, which mentioned "Fall: Chrysanthemums, maple leaves, willow, deer, kitsune" , but was curious if anything else fits?

Im also open to just not adding more, but as it stands, the majority of the work/non-background waves will be below or right above the knee. So I did initially agree with the artist that it seems like we could fit something nice on the thigh.

Thank you for any suggestions! Ive been googling around for ideas but honestly I havent had much luck. Also, Im trying to be careful to not break any rules that im unaware of. Any help is greatly appreciated!

Ill be happy to post pics with artists credit and the whole deal. I plan to ask if he's cool posting the art towards the end of our sessions.
