Question: What would you include for a character design?

I’m back again but before I get into my question I wanted to say thank you to everyone who commented on my last post as well as everyone on this form. I’m on a few different art-related websites and I’ve come across the kindest, most understanding people here. Y’all gave some amazing incredible advice while not being mean. Thank you.

On to the question!

I recently got commissioned to do a character design for someone and I am so excited. However, I’m not entirely sure what exactly should be included and if there is a general look, and I want to give my customer the best I can.

I have been given the looks (hair, clothing, accessories) and how they imagine their character but I’m wondering if there is more to character design. I hope I made some sort of sense here and thank you for taking the time to read this !
