Having some of the non-insect, animal-based riders portrayed as their corresponding motif would have been the path that I would have taken, but that would be too obvious.
I have completed Kemono Rider Faiz, a white wolf, since he is also the Wolf Orphenoch.
Also included is a glow-in-the-dark version. This was a good opportunity for me to practice light reflections, which I think needs a bit more work, but it's getting there...
