It's 100% the shader. You're using the cycles toon shader but with soft shadows; change the light settings so you only get hard shadows, also adjust the world setting.
The best results may come from a world setting of black, but you'll want a colored background (that doesn't contribute light), you can do that with a simple node setup like pic related (make sure the Globe icon is clicked)

Also I'm still using 2.78 so if the UI changed recently, I've been lazy about updating
