potential painting recreations

"Lady with an Ermine" Leonardo da Vinci

The light is coming from the subject's left, and she is facing the source.
I can place a soft box to the left of my subject and keep the right unlit.
I will need to duplicate the pitch black background and the ermine. I don't exactly have access to a ferret, so I will substitute it with a cat.
The angle is eye level to the subject, who is sitting down.
I will need thin beaded jewelry, a thin headband, and a thin gold band for the jewelry. I'll use a brown or black piece of cloth for the hair wrap, and dark clothing with a low square neckline, like a square cut shirt and a cardigan.
My friend Andrea; round face, pale skin, delicate hands and nails.
Andrea will have to hold her cat, Dude, in a manner that he will be looking to the source of the light as well, with her hand gently holding his neck the same way the painting's subject is.
The outer clothing, the hair wrap, and Dude's position will be the most difficult.

"Le Desespere" Gustave Courbet

The light is coming from what looks like a window to the subject's right.
I will face a soft box in the direction the subject is looking, and place a reflector below him.
I will need to duplicate the facial expression, hand positions, and shadows.
The angle is eye level to the subject, with them centered.
I will need my subject to just wear a plain sweater or button down, with his hair brushed back.
My boyfriend Preston; squared head, similar facial hair, longer dark hair, round brown eyes, white
The background will be plain and the clothing on the subject will be solid and simple.
The lighting will be the most difficult to duplicate.

"The Death of Marat" Jacques-Louis David

The light is dim as if the lights are out, but if the painting is brightened, you can see that there is some light coming from behind the subject, landing on his arm, shoulders, and top of his head.
I will probably be using a bathtub filled with sheets, so I will either use that natural lighting, or I will place a light behind the subject with the light dimmed.
I will need to duplicate the setting, the paper and quill, and the lain position of the subject.
The angle is level to the subject's position, but wide enough to see the arms.
I am using a female subject, so she will be wearing a nude top in order to replicate the shirtless subject in the painting. A white towel will be wrapped tightly around her head.
My friend Alina; white, lean
The background will be plain, but might end up having a window. I may cover the window with a curtain or sheet. The model will be slumped gracefully against the edge of the tub, still holding a sheet of paper in the same manner, the other arm dangling over the edge.
The lighting and background will be the most difficult to duplicate.
