Where is it?

Pen on paper using the one-stroke method. No searching lines and drawing in the shapes that could be shaded, but don't, to find the volume in the figure. No pencil, try to make the most accurate drawing without my usual guiderails. My success is uneven, I am so used to using searching lines and coming back in with a darker implement to emphasise and shade. UOOF, this one-stroke method is hard. Thanks for your aid and suggestions. All of the best, JCML Fine Art
