(First post in the forums... ever. I hope I get this right! )
It was a really tricky choice, you've created some really varied and intriguing characters and I liked them all! But I'm going to cast my vote with Lorenzo. I always tend to like quite and professional leader-figures with deeper insecurities, I find them really interesting, probably why I have quite a few OCs like that myself. Great job on all those characters!
Here are my OCs, for the brave person who wants to pay them all a visit: https://charahub.com/user/SkyScribbles
