ADVENTURES IN THE ELEVATOR (Concept)

I just got a new sketchbook and a set of color pencils. I've never used color pencils before and thought this would be a time to break them in.

This is a concept for a poster I have had on my mind for a while now.

"Imagine an elevator door opening to reveal this characters on their way to work"
