3D drawing for consoling little brother

Hello steemitians. Today after completing the stories, I went out for a walk. It was a cold evening, with mist on the grasses and a clear sky with a bright moon. Well life's good.
Anyways, when I came back home, I found that my brother was crying over a broken toy train. I thought, a 3D train can be a good idea. So drew a 3D image in a very little time with very less detailings.

P.S- It's a very simple drawing. The outlines are cut with scissor to give it a realistic look.

Materials used-
Art paper of routine thickness
Charcoal and coloured pencils
Black ballpen
Water colour
Round and rigger brush
