so thanks for your time

Finding the clearest picture possible would be a start.
I would do some measurements and check angles to set up a start on my page.
Then I would do a line drawing and map in all the tonal changes.
When that looked good, I would make decisions as to what medium and support I want to use.
Next I would transfer my line drawing to my good sheet of paper (support) and work from there.

I agree with Paulette completely.

To use a photo of this quality would frustrate you a lot. It might be ok if you wanted to do an impressionistic painting from it, but a detailed drawing? No.

If you want to use it for a value study it could work too, the choice is up to you. However, detail and seeing subtle changes in values are critical when using reference images.

Sinx, I think you can achieve good play of values in sepia-sanguine as well as in charcoal from this reference.Try a loose sketch of it and capture the position of the head and this is the most exciting part of it. Color in itself can be a good point that can make up for the lack of detail and that burning red and light and shadow are key elements in rendering a dynamic pose.
Most of all have fun.Art comes out of expriments and play in many instances.

if you are experienced in drawing you can "make up" shading after you get the line work done. Although it might look cool as a pop art or segmented type of drawing.

The first thing is for a drawing would be to convert it to black and white using "greyscale" in paint or photoshop. Then use a grid for the line drawing. Then begin rendering.

You could try using photo shop or other program to sharpen the image as best you can before you begin drawing. Also you could posterize this photo in photo shop that would help you with maping out the values.

Good Luck
