Nintendo really wants to teach you how to draw. They're sick of your stick figure Mario scribblings and they want to see improved fan art on the horizon. Thus, the Wii U version of Art Academy was born.
Learn to draw your own renditions of popular Nintendo characters, display them in your own virtual museum, and share your creations with others via Miiverse. Just don't be disheartened when you're not a regular Van Gogh on your first time out. These things take time.
