Monster Go Poster

An artwork I did for Office Contest "Video Game Poster" in 2014.
Where we need to create a poster of a video game we want to create.
Here, I want to "create" a running video game combined with hatching, grooming & battle of monsters gameplay.

Theme : Steam Punk.
All characters are my original design.

What do you think?
I think I want to explore deeper each character concept.
