The event that is a life session is always dependent on the relationship, whether very familiar or not, between the artist and the model. If it were otherwise it would be to make the sitter into an object.
The energy of a gesture and the unpredictability of movement are what fuels my enthusiasm for life drawing which is also the vehicle for ideas I use later on in my paintings. Clothing and the way it responds to the underlying form also carries a lot of information, not just about the suferficial, but states of mind like fear or shame. My own response to a sleeve which is too long and covering the hand , is for example pathos. This feeling of compassion affects the pencil pressure producing a different mark.
The evidence of these observations is a heavily Invested drawing however quickly it is made. I don’t draw anything else in the same way with such a sense of urgency. What is being drawn is an experience of humanity; points of recognition which spark in the unconscious and point to the mystery of being alive.
