Love the glowstick on his tooth. Also might be a good place to tie a human ;)

Thank you very much ! :O You have a great idea! :D I'll see what happens

I've seen phosphorescent colors or fur in some fursona designs; I love how they shine, whether it's mane or hair, like dyes, or some even have glowing tongues or paw pads that leave bright, glowing footprints when they walk.

Nighttime settings are certainly ideal for highlighting those characteristics; some even use tattoo designs with that glow. Using a glow stick on a fang, I admit, seems peculiar as an accessory, but if you like it, it could be an interesting design for your own saber-toothed tiger Diego. It's a pleasure to see more of his development. n_n
