 The paintings depict isolated figures enclosed in spaces that are <unk> , overwhelmingly <unk> , <unk> and eerie . Coming early in <unk> 's career , they are uneven in quality , but show a clear progression especially in how they <unk> and present ideas he was still clearly developing and coming to terms with . Head I ( actually begun in the winter of 1948 ) and Head II show <unk> pieces of flesh that broadly resemble human heads ; they have half @-@ open eyes and a <unk> , though it is positioned much higher than would be expected in a human . Heads III , IV and V show fully formed <unk> recognisable as men , and are characterised by a haunted atmosphere . These two broad ideas <unk> in Head VI , which is as <unk> tortured as the first two paintings , and as spectral as the middle three . In Head VI the figure has developed and is now shown wearing vestments , the first indication in <unk> 's work of the influence of <unk> , while the focus has become the open mouth and the study of the human scream .
