Absolutely! One thing that can make a character design more unique is giving them specific quirks, mannerisms, or speech patterns. For example, maybe your character always taps their foot when they're nervous, or talks with their hands a lot. You could also consider adding physical characteristics that set your character apart from others, such as a distinctive hairstyle or unusual clothing choices. Finally, think about your character's backstory and how it has shaped who they are today. What experiences have they had that have made them the person they are now?
