One of the main challenges of more or less realistic representation is to maintain coherence between the elements of background and figure, to create a spatial coherence.

In this exercise we will first propose a "set", wall, seat... in perspective where we will place a naked figure.

To draw this one, I suggest you to contemplate only the volumes, "forgetting" the skeleton and that our nude is generous of flesh (for a while I used this trick to hide the lack of anatomical drawing).
