This little guy is an OC of mine named Luca. He's part of a story I have in mind, something Ant Bully and Fern Gully-ish where a man named Jason lacks compassion for the little critters and ends up getting turned into a rat himself.

After that he meets the sweet Luca, and he begins to question everything he's ever known.

Very simple story, but I've always loved the heartwarming ones :3
