Cool stuff! Looks great!
Because this is using an earring slot - Could you modify the wearable to also include an earring or something to sit in the characters ears? This makes the item more relevant to the slot. Or if you change to Top_head you could have an item above the players head to match that slot. This is until we have more appropriate slot names for wearables like this.
For example - Collection 'Alpha Angels' created by ALPHAALVES#c9af is ready for review! - #9 by Billyteacoin
This item is a necklace but uses the top_head slot. And also features a halo above the players head.
If you have any questions let me know.
Cheers!
