Life Drawing: Mirror Man

My flatmate got confused at this drawing... (poor flatmate, no?) so to clarify - in case you too are confused... (it is probably quite confusing to people who aren't me... I'll give you that...) it is: the lower part of a man\s ribcage/belly then tummy with (he was wearing a piece of black string...) sort of his hip and his leg going UPWAYS. In the background you will see... a mirror in which part of his face is reflected.
