This sketch is about 3-4 years old, but I only just rediscovered it. If I remember correctly, it was inspired by a magazine cover of Rachel Weisz, though damned if I can find it now. I remember, in the absence of any art supplies (I was staying with my mother at the time), it seemed a fine idea to raid the fridge and see what I could achieve with ketchup and mustard.  I believe white-out was employed for the highlights and I upped the saturation in Photoshop afterwards.  The whole thing made for a funky afternoon.
