I need illustration of Characters from Titanic, 1997

I am in need of several illustrations of different characters from Jame Cameron's Titanic. I've attached some styles that I like the look of, so it would be great to have something similar to any of these examples.
I would like the following characters creating, which can be seen in the PDF attached:
- Rose - 3x different outfits)
- Jack - holding his drawing pad/drawing of Rose
- Elderly Rose - holding the heart of the ocean
- Cal
- Ruth

These illustrations will be going into an ebook that I'll be providing on my company's website, about video narrative. There may be some additional characters from Titanic that I'll need drawing as well as characters from other movies.
