Collaborative torn-and-repatched drawing

The initial idea of this drawing was to create a corner of a room (a spatial expression as required) by the different tonal patches torn from the group's drawings. The final drawing was not a pragmatic expression of space but rather a very powerful graphic gesture. I realised that tonal works though can help produce a sense of depth, hence space, could not accomplish its job in such pragmatic manner in which this drawing was done.
