Overall, I'm happy. 2 things I would change. First, the actual chain is way too short. It's practically a choker. I don't have a large neck, so this definitely wouldn't fit everyone. I have to connect it at the very last chain link to get it to sit where I want it, but that causes the pendant part tends to shift off-centre as the weight balances out throughout the day. Second, I would have liked the dopamine part of it oriented so it more accurately resembles how a chemist would draw out the formula. As it is, it's technically correct, but it would have been a nice detail to have it more accurately match molecular drawing conventions.
