Could we see your humanized take on Carmilla and Zestial? If you'd like! I thoroughly enjoy your Mimzy and Alastor stuff and will be cheering no matter what you draw. :)
I think Zestial turned out to be the least similar to his demon form in my interpretation 😅
I was mostly guided by his manner of speech for his human design (his demonic appearance said nothing to me about his era, unfortunately). He speaks in "Shakespearean sonnets," so I took the Tudor period for his character as a base. Given his stateliness, he appears to fit in with the clothing of the affluent of the era. And I decided to keep his long cape situation for mysteriousness XD
I'll add Carmilla later simply because I haven't finished her human design yet, pardon🙏
