Chosen Company style and decision on game layout

I have chosen Nickelodeon as the style choice for the 'game world' of the character as they have successfully adapted styles for various cultures and I want my design process to be the cute child style to be appealing for  the target audience.

As for game world layout, I have decided it as all 3-D as I want players to be able to click arrows and actually move into various spaces as if they are actually moving around it and interact with objects. The Shaman would be in front and demonstrating what various items, etc are, keeping to the cute style of Nick Jr to make it appropriate.
