I snagged this guy out of Adopt R Us not long ago and I'm off to a good start, but I'm struggling with his TC.... OTL

I tried to find an item resembling the stone necklace that Elias gifts Chise shortly after bringing her home, and I also tried to find an item similar to the stone bolo necktie that Elias wears but I had no luck. Other than those, I'm also out of ideas for what else to add to the TC.... (He's only going to have a 27 item TC for aesthetic reasons... also that's how many I can fit in the box I coded LOL) Any suggestions???

Also, feedback on the profile design would be great, I'm worried that the "dust" is too light and that I should make it brighter/easier to see? I was going for a misty/velvety look but I can make adjustments as needed, so please let me know your thoughts. <3 EDIT: A mobile test has indicated to me that lighting adjustments definitely need to be made. I'll work on that soon!

Thank you in advance for your help! :)
