Younger-ish Marius and typical nightmare age Lestat.
This is my attempt at drawing two white blond men without suffering same-face too much. I will say, in my present style for both Marius and Lestat they have similar noses and lips already. But compare them to how I draw Armand, Daniel, or Nicki and hopefully the effect is more pronounced.
Before I even read the caption I was thinking Wow this is a great comparison of the way similar looking characters can each be uniquely defined in subtle ways… and that’s exactly what you were aiming for, so kudos to you!
