'Conceptual continuity'

A usual drawing, fifteen years old:


But fifteen years later I create a CG-reproduction of this drawing.
Well, nothing special, but I was surprised, beacuse it's happen totaly unconscious.
I don't have view/remind the original drawing many years, but I have reproduce the same lines & construction, background, colors etc...:




*Sigh*, no real changes of style, subjects or technique the last three decades.
