Again! Brian, there are some who say they can recognise an individuals work, and I have often thought how? and in what way? because there is never any follow through by way of explanation.
However, your work, I can 'Ping', in moments. ( It's always the face) which is the primary visual of any piece. It always has a recognisable hue and shade, that makes it distinctly yours. (Blueish in hue, but subtle in contrasting colours)
