Career Zone project - concept art

The Career Zone at the university were looking for some animation students to help design and animate a short informative video.

I applied for it and ended up thumb nailing out a couple of ideas and drawing up some concept art.

I don't know if they'll choose it yet but here are some of the concept drawings
I did for them.

I wanted to go for a simple graphic style that would be easy to visually understand in seconds and perhaps simplify the characters to make them more anonymous.
