Research point - Foreshortening

I looked through my sketches and found these examples, both done in coloured pencil on paper.

The feet here aren't huge but they are angled down from the model's position on the couch.

and here, the other way round the feet are tiny. 

This Pinterest page has some good examples of foreshortening and some of the images remind me of sculptures by Ron Mueck which is neither drawing or foreshortening but was maybe influenced by the paintings of Lucien Freud (it all gets a bit too convoluted) Foreshortening is a device used well in comics
