Practise sketch 1 - Front

Practise sketch 2 : Legs, inside, trying to see what the back is...it's wrong. shall try to find more examples to analyse another day.
Argh this looks awkward and the proportions are off. Nevermind. Whole purpose of this is to draw shoes. Which is slightly off but...ah well.
