Pied Piper of Hamelin - Rat Creature

--3rd project of my first year in concept art at FX Barcelona Film School--
A reinterpretation of the tale: Pied Piper of Hamelin. In this retail, the piper is the one who drives the rats into the town, spreading the plague, and turning him into a fearful symbol of desolation that brings the plague wherever he appears.

Within the fog, a bony rat covered with a torn cloth appears in front of the people of the town. The ones that turn into rats follow this enormous creature through the black smoke, as if it were a parade marching through town.
