Nintendo hosted a contest for Paper Mario: Sticker Star and they asked fans to create and submit dioramas for contest entries.  The contest has since ended but here are a couple dioramas that fans put together.  I do not know how much time they put into these dioramas but I have to say that they look amazing!

The first diorama was created by Tumblr user ‘Finchiekins the Owl‘.  You can see more pictures of this stylish diorama at Finchiekins the Owl’s Tumblr post.

The second diorama was created and posted by Twitter user ‘gigideegee‘.  This diorama looks to be pretty large in size and is incredibly beautiful.  It is not as detailed as the previous diorama but it is still very impressive.  You can also see more pictures of gigideegee’s diorama in the gallery after the Tweet.
