I drew the line long time ago,then colored it recently for my CG class assignments.

The red hair girl named Robecca,she's a huge fire dragon before she got a magic then looks like a human.

The lizerd girl named Siren,It inspired by the siren in mythology,designed for a original comic.
She live in a forest,have a kind heart,can't talk but can sing. Her singing is dangerous,it can make many males go crazy.
