Very nice, I like the colour palette, etc. Interesting how Nick and The Fat Friar are both looking at the viewer and seem to be smirking while Helena and The Bloody Baron are both looking dead ahead with very serious expressions on their faces.
You know, I don't know if it was my insensitivity as a kid or what, but I never realised how mean the nicknames of the ghosts were. Apart from NHN, but that was because it was blatantly put that he didn't like his nickname.
it's a fine balance of knowing what to take from reference to make it read and knowing what to add from your own visual vocabulary to make it better that something you can normally observe (this balance will help you visualize your voice, and allow it to feel natural when in use)
I think that when you see a character from a movie, you analyse her physical aspects and learn how to recognize the character face from 1000 others. Does he have a big nose? Pointy ears? A small chin? Like how can we recognize Batman: black mask, pointy ears up to it, pointy and sharp nose, white eyes etc.
When you want to draw any character you saw, you feature those characteristics because that's how we can recognize him.
Then again, that's just drawing style. Imagination comes from everywhere: music, books, movies, your friends, your love, your life
AWESOME! Sir Nicholas looks especially dignified, with his neck in place and all XD I imagined the Baron ENTIRELY different, with a ragged powdery wig and sunken eyes....never would have thought of him as a mustache guy...
